Telkom - Worst Experience Ever (5 months and still taking my money)

Good day, i ordered a device online on the 1st of May 2017, i was told the device would arrive in a weeks time. No communication was then given to say my order had been approved or the way forward, 3 weeks later i got the device delivered to my work address. i immediately visited a Telkom store which was extremely unhelpful and unpleasantly rude, telling me i cant return the device and i need to call in to cancel. Eventually i was able to get hold of an individual at Telkom, i then returned the un-opened device on the 31st of May 2017 (Cancellation form completed a week before), less than a week after i had received the device. i got confirmation that my contract had been cancelled, thus i was extremely surprised when i continued getting billed for the device for the months of, May, June and July (my contract was supposed to be cancelled and May bill credited). i have been in communication with the individual for 5 months and he has now referred me to someone else, who obviously is now not responding to me. 5 months has gone by and i still haven't been credited for the months i paid for this device i have already returned. I have been extremely patient but this is a process that has been highly frustrating. Never again will i deal with Telkom! The worst service i have ever received!! It is now October and i am still running around for R2000.00 which was debited from my account 2 months after the device has been returned!
