Wrong Service Plan

I have been a Telkom customer for years, it was nice no problem. But the he third time I'm renewing my contract and upgrading the sales consultant gave me a wrong contract he just did a service plan I do not want. Now it's been almost a month since I have enquired with them about my service plan I haven't gotten any feedback whether they working on it, I take it upon myself to enquire with their consultants every work with regards on what's happening and what is a way forward.. I just want feedback and a solution from Telkom as now I'm paying for a contract I'm not enjoying its benefits at all. I am not happy with their poor service. If there was any feedback from them it would make things much better
