Telkom is so unprofessional

I moved to Soweto in February and my phone suddenly had no signal, I have reported this so many times to Telkom but still there is no improvement. So I decided to tap into my savings so that I can settle the account and move to prepaid. Since Thursday I have been calling about cancelling contract and every agent is telling me a different story. This in a huge inconvenience as I am using this phone for work, I have already received several warnings because they think my phone is always switched off. TELKOM PLEASE CANCEL MY CONTRACT, I need to use my phone again.
