Mweb Fibre Direct Debit Date - 9 Month Dispute

Since September 2020 I have had endless problems with Mweb Fibre and their link to Vumatel in Grassy Park. Each and every month my direct debit goes off on the wrong date and I get cut off at 12 AM in the 21st of each month. I work night shift remotely from home. Everytime this happens I either need to make an immediate payment, get into my car during lockdown and head to the office or head to someone else's place to work from there. It is an ongoing issue which according to Mweb has finally been resolved this month in June 2021 but not shortly after I have been cut off on the 21st May 2021. I had to make a double payment to have my line restored. I have waited 10 working days for the refund and today I was told another 10 working days. I have just had enough, for all the problems I have been having the best they could offer me was 1 months line rental free and a direct debit bounce fee. Honestly I have suffered as a consumer for 9 months to change the direct debit date which I was told is possible. My customer journey is putred. The amount of money I have spent and loss of income due to the lack of service is not fair on me as a customer. I am at my tether and have no faith in Mweb
