Slow service

I was referred to TTT from a friend and all I wanted them to do is my rebate and change my bank details. I contacted TTT on the 5/8/2020 and today is 29/9/2020 and my rebate is still not paid into the account. They paid into the old account. Many emails have been sent regarding waiting for sars to respond and it can take up to 21 days but I have been patient and the 21 days is over and the issue still is not resolved. I would not recommend TTT to anybody
