MWEB poor service

Very poor service, the sales department is the worst. I have logged an order on the 29th November and suddenly when I was doing a follow up, my order was cancelled. In that same breath zoom fibre came to install fibre on the 11th December just after I was informed my order was cancelled. Then I tried to find out what us going on here, then the same department created a new order, suddenly when they have to activate my account, they request a cancellation number from previous ISP, which I do not have. I explained the whole story to them that my 1st order was cancelled the a new one was later created as Zoom has already installed the fibre but still they were unable to activate my line. I waited for 3 months, calling them every single day. Then decided to cancel that 2nd order, now I'm still struggling to the cancellation confirmation letter in order to provide it to my new service provider. When I call to follow up on the letter, I will get to be transferred to another department, then the line will be disconnected after holding for 15-20 min everyday. When i ask for the contact number im always told there is no contract number or an email for that department. I am so, so frustrated with the MWEB service.
