Unhappy Tymebank client

I had opened up an account online with tymebank in may, downloaded the appAnd could log in. Trouble started when I had to update the app upon trying to log in i put in my id and pin but then its this OTP i I should get from my old number Acc is active but needed to deposit money and make a debit card at the kiosk. I then changed cellphone numbers and went to a kiosk in one of the pick n pay stores selected the change my number option , got an otp on the new number then gave me an error mesage. The Tymebank ambassador who was at the store called the call centre , person we spoke to an agent who said they wont be able to change my number and would have to lodge a case. As im on some good friends profile. I have tried changing my cell number from the beginning of October but still to date nothing i further received an email on 31 October at 10:28am stating that a case has been lodged and i will get a response latest 3 November at 1:09pm latest . Well that was just a mail nothing fruitful came from that. i have 15 OTP messages from tymebank, have visited atleast 6 stores trying to find a kiosk that has network but to date nothing has changed nor can i transact on my account as i require an otp to authorize any transaction i want to do. I actually feel ****** of my time and money as i just require my cellphone number to be changed so i can use the acc i have spoken to about 3 agents at the call centre after holding on for about 15mins before call gets through. And everyone i have spoken to cant assist even if i ask them to close my acc and then i can go open an acc via the kiosk i was told that i can never do that once acc is closed its closed forever. Thought this bank would save Tyme but guess never knew changing a number would be such a drag
