Unacceptable service delivery.

I had to hang my modem outside my house and still had poor signal. When I complained in November 2014 MTN said within 10 working days they would attend to the problem. After one month I contacted them and still no response. I wrote e-mails phoned and was promised that the coverage supervisor would phone me. Nothing happened even up to February 2015 and I requested them to cancel my debit order because a normal bank transaction sometimes took 30 to 40 minutes(if I could get a signal at all) and I had the risk of rain and theft. Then they just kept on billing me as normal. I stopped using the modem and stopped paying. Now they handed me over to the attorneys without addressing the problem.
