Fake FBA Orders

Hi Everyone, I am UAE based seller, selling on amazon.ae. I am a first time seller, started selling my product 3 months back. In the last 1 month I have noticed there have been quite a few order that have been returned due to “wrong address” or “refused delivery”. The number of such orders is quite high, its almost 28% of the orders. All these orders have not come through amazon ads, since my product is new I am still not ranking organically on page 1 for any keyword, so all my order apart from these orders have come through amazon ads.

So thats why I feel that someone is doing this on purpose. On all these orders I am paying the FBA fees. I have raised a complaint with amazon 3 days back, still waiting to hear from them. Has this happened with anyone and what do you think I can do? Any advice will be highly appreciated.
