I think there are several actions you could take to minimize the risk of getting cases opened against you. As eBay is unlikely to change their policies anytime soon, it would be in your interests to avoid cases getting opened in the first place. Even with the 8 bogus cases, that still leaves 7 cases opened against your account. That is too many. At this point, your selling privileges are at risk. Ebay policy may be grossly unfair, but right now you don't have the luxury of arguing the point with the platform. On some level eBay will require your cooperation to limit cases in the future.
The most expedient change would be to accept returns, buyer pays return shipping. Ebay may offer No Returns as a choice still, but the reality is you could be getting penalized for saying you do not accept them. It makes good business sense to state you will take returns since you do anyway. In your terms of service, you encourage buyers to reach out to you if there is a problem, and you mention returns. I imagine you have accepted your share of returns to satisfy a customer with an issue. By having returns, this does not necessarily mean your return rate will escalate to some scary level. I offer free returns for many years now, and my rate has not increased an iota. I very rarely get one. But I have also never had a case opened against me in over 10 years of selling.
Another action would be to drop the entirely unenforceable, long-winded terms of service, and put the item details first in the description field, as another poster advised. I would also omit any references to feedback as eBay considers such references in the description as feedback manipulation, and it is against policy. (Many sellers are unaware of this rule. See Feedback Manipulation policy.)
I also noted this phrase in your condition field, "Please read item description carefully before purchasing. Please note as per resale law the label on this item has been snipped / removed. This is to avoid fraudulent store returns.” It is important to mention the delabeling to buyers, but what law are you referring to? It can be a requirement by certain retailers when selling shelf-pulls or overstocks to resellers, but I could find no federal or state law that mandates this.
You mention restocking fees in some of your listings. These are not allowed anymore on eBay. Sellers also cannot withhold shipping costs on returns when it is a free shipping listing.
Adding basic measurements to clothing listings can help minimize customer issues. This is a time-consuming task, but I also would absolutely give such measurements in inches as well as centimeters.
From your descriptions: "I don’t provide free return. As a single mother work full time in a daily office, I use a warehouse supplier to handle all my dispatch and return, they charge me 5% on each return for re packing and re stocking. Thus your refunds will be given less all postage charges and 5% return handling fee." This phrase alone could be responsible for cases getting opened. It is not enforceable, and as mentioned, sellers cannot withhold restocking fees from refunds. A buyer with an issue will bypass a recalcitrant seller and go straight to eBay's Money Back Guarantee.
It is not a good reflection on you to have policy errors in your listings. Nor having suggestions urging buyers to not buy from you. It does not build buyer confidence, and does not protect you in any way either. Right now your listings sound fear-based. Long tedious lists of terms do not protect you. Ebay's Money Back Guarantee trumps all seller terms and renders all your many warnings and threats to report moot.
Consider instead doing a complete overhaul of your listing terms, replacing them with buyer-friendly conditions. Use a little shopper psychology and a change of attitude to encourage your shoppers to buy, without the fear-based rhetoric lacing the description field. You are a successful and active seller with great items. Your listings should project that reality instead.
