Disgusting customer service!!!!!!!!!

I am extremely upset and disgusted with the service received from Mweb My Debit order is set to run on 20th and has been running for the longest time/years now. They decided not to run the debit on 20th a working day mind you, but the 27th or the 29th, for what? I WOULD LIKE TO KNOW!!!! they sent me an email on the 27th of an unpaid, upon replying to the mail I received another mail confirming this was an error. I have been trying to make telephone contact, and you hold forever and a day, there chat line is just as useless. they have the NERVE to close my fiber connection without any discussion, OR MAYBE THEY KNOW THAT THEY MESSED UP AND IS AVOINDING THE CALL CONVERSATION!!!! who is to blame for this nonsense. I right now i am on line for 40 min, caller nr 4 for the longest time. CAN I GET THE CEO to contact and explain this **** service with immediate effect!!!!!!!!!!!
