Forget fibre

I had vuma and informed them i would be moving they said they would cancel the line and i had to get a new line at the new address. I got the new line installed after a month. Meanwhile i made 2 payments to incorrect lines as I didnt have the correct information despite asking them numerous times. I cannot speak to them only on WhatsApp where i get terrible service. I have asked for payment allocation ive been without wifi for a week now despite making payment. I want to cancel and request a refund and i cant even get that right on the WhatsApp because i keep getting different stories
