THE WORST SERVICE EVER

The worst service ever .in december 2020 i started phoning vodacom requesting that my 2 contracts to be cancelled,the 1 was already finished while the other 1 wanted to do a premature cancellation,after several calls i was then given a quote and i went to clearwater vodacom and paid and i asked the staff to call and see if i have paid everything and was then told that i owe an additional R515 which i paid and sent proof to the cancellation department.it is now march and the contract is still not cancelled,this morning my account was debited again after i clearly expained that im no materninty leave and im not getting paid hence the cancelation.i have been calling on a daily basis and everyday no 1 can provide me with answers ,when a call im being told there is nothing they can do about my situation and that matter has been escalated ,im frusted as i need to get a cancelation letter in order for my home loan to be approved .
