Aliexpress and the band of *******

I have to start the story at the beginning. Six years ago I suffered kidney failure from training incorrectly for The 2 Oceans Trial run. Too much salt, too little water, too little attention. Since then my running has become walking and lately the only sport I can do is riding on my home built e-bike. Being competitive by nature I was excited to being able to enter the Cape Town Cycle tour on my e-bike. Problem is, will my battery last? To try and get that question answered and the fact that e-bikes are expensive and new concept, I bought several batteries from Aliexpress over a period of months. Here is where the story of extremely poor service starts. I have been doing business with Aliexpress for years. Generally the product was delivered or refund given. Now as most knows, our post office is non functional. So importing anything has been a disaster. After payment, Aliexpress notifies me of shipping and the transit of the package which eventually ends in delivered. To make matters worse they say they delivered it to my address. Not that I receive anything, but they delivered it. To where I still have to find out because they never give a signature or a place where they delivered it, no matter how much I ask. They require the Post Ofiice to supply me with missing proof of parcel. Which is impossible. They never give a South African tracking number - so the post office will never give you anything because their tracking number does not pull through. So one is stuck without proof and without anything. Eventually, no matter how much you corresponds with Aliexpress, they always rule against you. I corresponded with the post office (local, area and provincial), with customs, phone the Post Office Help line several times (never an answer), held on for more than an hour (no answer), contacted their shipping company in china, contacted the seller, proved that the post office is non-functional, even bought some stuff at Amazon to see how they do it. All in vain. 4 Batteries bought, non arrived. I even went to buy loose batteries from a seller that uses DHL, only to have it changed to "sellers own method" and resulting non delivery. Aliexpress was deaf to my 17 proof documents maintaining their supposed delivery which didn't even give an South African tracking number. It suits them never to answer your questions about - prove delivery. No you, the client must proof non - delivery. What absolute hogwash. A non legal concept. Not 8 months later, I will never buy from them again. They never ship to your address and our Post Office is defunct. For me the worse, is that they always not pay out. Protecting their trader, against the paying client. I have a 48 page document that backs up everything I say
