Telkom

We are struggling for almost 9 months with telkom .we had a package for our ADSL line and a laptop with a ****le . 1st the ****le was/is included in the package and they bill us R233 if iam correct extra on top of the bill were it is supposed to be included 2nd the package also includes a 4mb ADSL line but never got the 4mb we barely got 1mb .were our contract said 4mb . Last year 2018 August once again the line was offline we went instore to cancel the line and also we moved but main reason was because we never got a 4mb line so we are not paying for something we don't get. The lady instore said we have to give 30 day notice and we did then we will only pay for the laptop and nothing else. Now Telkom handed me over to debt collectors to pay for something we don't have for 9 months. What to do next?
