TGF Foschini Chatsworth horrible service/ *******

I purchased a phone(Hisense) from this store and was informed if there are any issues it can be returned within 7 day for a new phone or refund. So upon having an issue with internet i went to the store and Kerusha did not want to take back the phone and said that it is a 3G issue so the cannot return. I told her her manager Ashraf told me on day of purchase i can return within 7 days as long as no water damage or neglect to phone. I stood firmly to the agreement and after Kerusha going to back office a few times they gave me another phone. This time it was a Huawei same 7 day exchange plan but this issue was about day 10 there was a major problem with that phone as I could not answer as the phone rings but no opinion to answer or decline call. I took it back and the sent it in for check up and told me it could be up-to 21 days, so issued me with a loan phone with did not function properly. I had put asseories of R300 on phone and did show them. I waited 21 days and phoned the store and was told Huawei did not acknowledge my phone(meaning that they didn't look at the phone yet) .Since that moment the service got even worse as the promised to call back and keep me updated but barely did. Amelia informed me about a week later to take a new phone. I phoned the store 36 times in 1 week but no answer. The store manage Nicolas ,Kerusha and Amelia was supposed to call back but did not up till today. So I phoned Foshini customer service to report this a lady by the name of TK assisted I explained what has happened and she said this is not how TGF treats clients. 5 days later I went to the store same cold treatment and was informed by Amelia that TK did not contact them ,so I told her phone TK now as we discussed a voucher to replace the extras I put on the phone. I told her I will be back for a update so when I got back still no update. Amelia just picked up her phone dialed and cut call and told me H/O is not answering And will update me by COB 28/7/2020 . This I horrible service and I have been very patient and had enough of Fishing Chatsworth.
