Appalling service

I went to Telkom Mobile Liberty Midlands mall to upgrade my cellphone contract on 23.02.2019. Unfortunately the device I was given was faulty and I resorted to cancelling the said contract and requested that my existing cellphone number be moved to prepaid. I was told that this process would take 7 days, meaning that it would be resolved by 01.03.2019. On 01.03.2019 I went to the branch and spoke to the same gentleman who had been assisting me with the upgrade, and was advised that the contract had been cancelled, but instead of moving my number to prepaid, my cellphone number was cancelled. I was assured that the number would be retrieved and put in my name within 72 hours. It has been 4 days and nobody has come back with an update, regardless of my many phone calls to the call centre and empty promises to keep me updated. I'm am absolutely appalled at the poor service I have received and do not see myself staying on this network if my number is ever retrieved.
