Complaint

So I have a complaint going on for 4 months. My initial complaint was the poor quality speed that I was getting on my LTE router. I cant even get 100 kbps. I think the old dial up connection was faster. This still has not been sorted. I then updated my banking details and for two months my debit order still did not go off. I have been paying manually in a store. Now telkom tells me I owe them 1300 rand as there was a technical error. I have never seen such a **** company like telkom. I canr evrn cancel my contract as I need to do it online. Its like they make it so difficult for you to cancel so they can make a peraon broke by their ****s. Telkom is the worst service provider. Bunch of *******.
