Terrible Customer Support

Awful experience overall. We were on a 10mb month-to-month and came in-store to cancel and upgrade to a new plan. The lady at the front has got to be the worst customer support I've ever met. Arrogant and rude. It was clear that she had no training whatsoever. I told her that I needed to upgrade my line because I would be working remotely, I was then told that I'll have to go without WIFI for a month to process the cancellation. So the best response to catering for a customer who works remotely is to strip them of their internet connection? I did state that I would be willing to pay for both the current and the new plan in order to ensure I have a stable connection to perform my job. The new plan was then processed and they began the cancellation process, which to be knowledge was being handled by this lady. Again, I stated that I was happy to pay for the additional R270 that month to ensure work went on smoothly. A week after paying the R1000 to get the new contract running, it went down. I called in and that same arrogant individual answered, took down my details, said she will call back, and never did. I got an SMS saying that my query was completed even though I still did not have a connection. I then had to phone their customer support line to be told that the payment of R270 did not go through so my account was suspended. So the person handling the cancellation, cancelled the debit before ensuring the subscription was cancelled. So now my credit score has been affect because of a level incompetence. I paid the fee but my router is still now working. All-in-all, I paid R1270 for 5 days of stable internet. The sales agent is amazing, I would fully recommend her to anybody! She knows her products and is an amazing human to boot. But the attitude of the support staff at the front desk and on the call has really left an awful taste in my mouth with regards to MTN Coastlands as a whole. If this is the level of staff that would be client facing then I cannot in good conscious recommend this place to anyone. I will have to go to another service provider now to take a new contract. What a waste.
