Keeps disappointing

One service provider who just never make effort to offer better service, let alone follow up even if you complain in store. I requested cancellation of my contract and was charged R1920 for it which I paid same day, instead of invoice stating final bill it shows expectation of another debit order to still go off in the new year. I have been on call for over an hour trying to resolve the matter but im being sent from one agent to another now I have been listening to the irritating music for 40min now. Worst part u go in store n they tell u cancellations are done by calling yet they never answer.
