MWEB - Ridiculous Call Centre Waiting Times - No Other Options Available

I have been in the queue with Mweb for over an hour now trying to change my debit order details. Absolutely no customer service, I have been disconnected twice and found there is no customer liaison via email with them. I haven't received a single OTP since installation and somehow, they believe this efficient for their customer. I tried the chat option; I've been sent a supposed OTP. So I had to send an alternate address and still waiting for an agent to reply for over 40 minutes. The utter inconvenience of waiting in a queue forever for a simple request that can be sent via email correspondence. Once again as South Africans we are subjected to absolute disrespect from providers that are being paid for a service!!!!
