Cancelled account still receiving bills - ****************. Staff have a pathetic attitude

Very easy to open an account. Impossible to cancel. Each time you go into a store you are told you are too early come back next week. Finally managed to fill out a cancellation request on 25 November 2017 in Sandton. Ref ********** 0. Agent so rude had to literally beg him for proof that I had been there and competed the form. Emailed cancellations 3 times thereafter. Called the customer care line too. Keep being promised that a manager will contact me. Tried the community chat today, agent Berry just dropped my query, agent Sarah said - Berry says this is the last invoice, when I asked why I was still being invoiced in February if I cancelled in November she said 21 working days and dropped my query. I feel like Telkom is *****ing from me. Absolutely disgusted with this lack of service and poor attitude. Worse thing is that when you cancel you get charged for a full month but they cut your data at any given time. No warning at all!
