TERRIBLE service overall- Bayside Mall Store

On the 23rd of September 2017, I cancelled my Telkom LTE service as it did not live up to what was promised. I was hardly ever able to make use of my internet and yet I was still paying R699 monthly. I had popped into the store a week earlier to discuss cancellation and a lady by the name of Sasha assisted me. She stated that I would not be charged a cancellation fee nor any other fee and the only amount I would be liable for would be my latest bill. Back to the 23rd of September. My partner went into the store with the LTE router as advised by Sasha. I was emailed the cancellation forms by a man named Thaabit. I filled them out and sent them back as instructed. In the emails being sent back and fourth between Thaabit and myself, He confirmed, in writing that I would not be charged a cancellation fee nor any other fee. ( Please let me know if you would like a copy of the emails ). Thaabit stated that he would ' need to motivate for complete credit of account as we could not deliver on the services promised to you'. On the 10th of October I received an invoice saying that R1015.61 was due and on the 31st of October this was successfully deducted from my account via debit order. To my surprise, I received another invoice of the 4th of November 2017 for R699. As far as I was aware my service had been cancelled and I had paid all due amounts. Once again, I went back to the store and this time spoke to Ronwyn. He wasn't too sure what was going on and he called Thaabit. I was now made aware that no cancellation had ever been sent through as promised by Thaabit. He said he would submit it and stated that I wouldn't be charged the R699. Sure as the world, on the 30th of November I was charged R699. 4 December 2017 -Back to the store I go AGAIN. This time I stand in a line for +-25mins until I am assisted. The man that assisted me literally told me that it was a billing issue so he couldn't deal with it and that the contact center would call me to sort it out. The contact center calls me- what a frikkin joke! The woman on the other end of the line firstly has absolutely no idea of what is happening and keeps telling me I'm confused because I had not cancelled and I would be charged. When ever I tired to talk she would shout over me. She then says she is transferring me to the Cancellations department. I wait and I am cold transferred to 'New Business' ( I'm assuming that's Sales ). I go BACK TO THE STORE AGAIN! I stand in the line again. Eventually its my turn to be assisted and I tell the man my story. He immediately tells me I will not be refunded nor would he give me confirmation that my service has been cancelled as 'he cant do that'. I ask for a Manager and am told 'I will see if there is one who isn't too busy to see you'. After about 5 mins, the same man comes out and tells me he will be submitting the cancellation and refund request and sent me a case number. Now I have received ANOTHER bill. I have in writing that I would be charged nothing more than my last bill of R1015.61. I don't understand how I am being charged for a service which by fault of Telkom has not been cancelled and how the hell am I being charged for usage when I handed the modem back to them. I want this fixed ASAP as this whole issue was due to the incompetence of your staff.
