the worse service I've ever experienced

The most appalling service ever. Towards the end of march I was that I was still being over charged on my account. They even debited my account before the due date. I reversed the funds and made a payment of what I am supposed to be charged. Now they threatening to cut off my services. Telkom owns me a credit for the days I was disconnected in march, I was disconnected for 2weeks. What must I do yo have my account fixed? This is my 3rd complain on hello peter clearly this is not helping. Must I try another platform. My 1st query reference number: ***1 2nd ***, 3rd *** after paying my subscribtion they said I still owe: R349 and that's an overcharge for something I don't even have access to use. My new query is assigned to Lambart Makhoza. I would like to speak to his manager.
