Unsatisfactory service

when upgrading my cellphone account, sale lady entered incorrect code, resulting in me been given incorrect package. She then logged a case (***8) and I was told it was sorted and I would not be charged as it was Telkom error. I was then billed R5940 fees. <br> there is an email stating im not to be charged these fees, yet I was. <br> I have 3 cellphone contracts with Telkom and they have now all been suspended due to Telkom messing up my account.<br> I called billing and they say they will try get back to me in 48 hours.<br> this is unacceptable service as customers should not fit the cost of suppliers faults.<br> I am now without any service on all 3 phones but will still be billed.
