poor service

I upgraded my cellphone in May you had all my documentation on hand including banking details<br> They send me a message saying I owe 300 odd I pay shortly after hey send message saying I owe 1100 odd I ignore I call callcentre phone gets dropped numerous times after holding for long time.<br> My phone gets blocked they pull they 1100 odd from my account without explaining where and why they unblock my phone<br> <br> How do you block my phone when I am paying how do you withdraw 1100 odd without explaining to me in the same month why and what its for where does this amount come from and you cant use the banking details as an excuse as you clearly have it<br> <br> Then i get a call from Mlungisi asking if i want to upgrade my phone<br> <br> I need answers i need them before close of business tomorrow, this is highly unproffesional and upsetting I have a day job I WILL NOT VISIT A BRANCH i work for my money<br> <br> This is a huge huge inconvienance
