too many stories on their billing side

Please be careful when thinking of signing up with Mweb . Their billing department is terrible . On about the 15 February 2019 I put in notice to cancel my adsl line as at the end of February 2019 . I was advised that they would bill me for March as I had to give a months notice which I agreed to . I then opted for an LTE line .I was told that it would take 10 days and they would immediately stop my contract the minute I received my router and I need not worry about paying for March . Never the less I ended up cancelling the LTE line as the service was non existent . I received a letter from them saying that they were sorry I was not taking up the offer of LTE . They then took money off my account again April , May , June , July and August . I have called them on several occasions and it is always different stories . In May it was that the Adsl was only cancelled for the 1 June 2019 . On querying this they said they thought they had made a mistake after I asked them why would I phone middle of February to cancel a service in June . They said they would check up on this and come back to me . NEVER DID . Then when I called again as they deducted money I got a message from one of the customer care to say they will sort it out . Still took my in August . Today I called and suddenly I was suppose to have sent them a letterhead cancelling the service and then got told they actually charging me for the LTE . They havent even given me a router so where do they come on this now . I had called 3 times to make sure the LTE and my adsl line was cancelled and it was confirmed . My son cancelled his service 6 months ago and is still being billed . Seriously dont support MWEB . We are going on fibre now and they certainly wont be considered by me or my son .
