Cancel my account and reimburse me

Hi there, <br> <br> I would like you to please cancel my Telkom ADSL line due. <br> I got a 4MB line installed in 03/2015 & from the beginning I never got speeds above 1.8 MB. <br> I reported this many times and >5 technicians came to my home to confirm. They all promise to get my line speeds and billing decreased to 2MB. This never happened. I lost my patience and then called the call centre and a dispute was logged on 04/06/2015 (***). On 13/07 I then got an SMS asking me to visit a Telkom store to downgrade and to get a differential credit arranged. I visited the store at Greenstone Shopping Centre that weekend and the forever confused staff couldn't help. <br> <br> On 03/08/2015, I got an SMS that my account was suspended due to arrears. I called and told your agent that I refused to pay the arrears due to my differential credit that was never given to me. I then asked her to cancel my account so I would no longer be billed. She promised that her manager would call me back to arrange but that never happened. Yesterday I got billed R770 for a month where I had no service & I want my money back. <br> <br> Please also resolve this: hellopeter.com/telkom/complaints/technician-wall-***
