Trying for the fourth time to manage few things on my account and still no luck

I phoned Telkom 2 months+ ago. Telling them I wanted to cancel I contract. First they said I can't because the contract had not yet expired. However I took out that contract when 8ta was still around. Then they said I must wait 30 days, if nothing happens I should phone back (why should I phone them shouldn't they phone me?...but ok I did). They then escalated the cancellation request so that someone might see it I guess?! They said a manager would phone to help me. I guess the manager lost my number, he never phoned. I phoned again...they escalated it again..nothing, again. Then I tried to follow the online route. Submitted my cancellation and required docs, but still nothing! This service is terrible. I also saw my bill was invoiced more than it should, I wonder how long it will take to sort this out. Telkom you should be better
