Telkom still has not resolved my issue!

Below you will find my previous complaint report. They phoned and said that I can cancel this contract at any time and that I should send the cancellation letter to a specific email. I followed this procedure perfectly and got an email with ref nr ***5 and they said sorry they took so long to respond. Every month they kept on deducting the money to the point where I stopped the debit order. Now they claim they didn't get hold of me and I can not cancel the contract. Please can this be resolved urgently as I asked for the superior to phone me and almost a week later no call...<br> <br> I lodged a complaint that my data sim card keeps losing connection and at nights I get no connection at all for the last 2 months or so. I got a case nr ***8 and they were suppose to come back to me in 3 days, it has now been 2 weeks and their excuse is they could not get hold of me but I have had no missed calls. I have been with them for 3 years and this is the worst its ever been.<br> I was told that they should never have sold me the contract because there is no signal, but on their website they show 3G signal at my house in Hartbee****rt, but they say the data signal differs from the voice signal.
