Mweb - Worst Customer service ever

It is unfortunate that there are no minus numbers for stars! I have been a loyal customer of mweb for 7 years, I have brought many more customers to them. I have recently discovered that when your Fibre line does have a problem, there is absolutely no way of getting hold of them. At first I was trying to report the problem, their app will not allow you to do anything without an otp, unfortunately this never comes. I have spent R100's trying to get through to there technical department but they just put you on hold (talking hours here!!) Then I tried their social media, went onto FB, sent dm - no response!! So I start complaining on their posts - they blocked me (I'm not sure how they figure out who to block as ALL the comments are complaints!) I then tried sending an email to cancel my account - no response. End of the month comes & they are still deducting off my account - I had to get the bank to reverse the debit order. I know that in South Africa, we have been trained to accept bad service but this company takes the cake, someone should shut them down! They are ****s and ******* - do yourself a favor, do NOT sign up with them, I promise that you will add a few years to your own life with the stress that they cause. God on their social media, read the comments and believe them, they treat their customers like jokes.
