Customer Service is Shocking

Mweb you used to be a good company - what happened? Your customer service is atrocious... I changed my phone number (people do that - really) and I have filled in all the forms sent copies of my ID - more than I was asked for from my bank even and yet STILL I cannot get a one time pin because you continue to send the pin to my old number and disturb the poor soul who has my old phone.... My fibre was down for 5 days I called at least 30 times, did the same troubleshooting each time, but no luck then the supervisor called to say she would sort it out and call me the next day - that was about 2 weeks ago - the fibre is somehow working but NOT a WORD from anyone at Mweb. Today my speed is down to 2 Mbps on a 20 meg line but I gave up trying to get help - 28 in the queue!
