Telkom a big **** be warned

Telkom sa is a ****. I app**** for a LTE mobile which was delivered to me on the 20 March 2018 when I received it never picked signal at all. I went to Cape Town on the 10th April to a telkom retail store and I reported the case. The gentleman looked in the system and explained that the area that I am staying in has no signal and the device was not supposed to be approved in the first place and he suggested that I should cancel the contract .I immediately contacted telkom and I spoke with Mbali Simelane who explained that i need to complete the cancellation form and it will be cancelled automatically which I did and emailed it through to her on the 20/04/2018 and I have evidence that it went through. To my suprise the deduction went through 2times the following month. I again called telkom and I spoke with silindile venacia magwaza on the 16/05/2018 she suggested the same thing that I needed to complete the cancellation form and it will automatically be cancelled and tha they will come and collect their device again I told her that I have already than that but she said it will go through. Again I completed the form and I emailed it on the 16/05/2018. On the 24/05/2018 I made a follow up to check whether I had been canceled . I Phoned telkom waited for about an hour or 2 as usual and I finally spoke with Masingita who confirmed that nothing has been cancelled from their side frustrated and angry I asked her how is that possible despite numerous calls and waiting so long to be transferred to the next available consultant and my money being deducted whilst I m not using their deviceand it went through but again it deducted the following month. Again she said I should email the cancellation form through to her she will take it to her supervisor cause she cant cancel it from her side. She then emailed me back and stated that she has sent it t o her boss and it's now cancelled. The following month June telkom deducted 6 times the agreed upon amount from my account. I went to the bank I reversed the amount and I tried calling them but couldn't go through as a result of long waiting times. Now telkom keep deducting everyday from my account despite numerous attempts to cancel their contract due to their poor service because as it was explained by the telkom agent ,they were not supposed to approve my contract in the first place based at my location instead they were greedy but approved it anyway. I would like that telkom cancel this mobile contract and provide me with my refund
