The RunAround by Telkom

Hello Im not writing this because I have nothing better to do. Its taken some effort and time to get on this platform to express my disappointment with Telkom. I had a 2yr contract for mobile wifi (10GB) a month. After paying for 10mths, I decided to upgrade during their May 2018 promo to 20 GB a month and I got a second device (Huawei B315) . My monthly payments were to include the cost of the previous device. I conducted to transaction at the Gateway Telkom. I made it very very clear to the assisting agent Philani that I cannot pay the once off fee and he told me R30 rands will be added to my monthly fee making it R306 a month. But the following month R1800 was debited to my account ( which I had not budgeted for!) On calling the billing dept and online help I was told to go to gateway branch and see Philani to sort. I went to Gateway (paying the parking fees and my time) and was told by Philani to go to Telkom webside and ask for a call back to sort out. So I have been given the run around. To date 24/08/2018 I have gone back to Gateway 4 times and had callbacks 5 times. Last time their computers were down and was told the agent will call me back. He was sent an email to do so. As yet I have been ignored. I simply feel like I have been ****** by a big business with nameless bosses.
