Internet from good to worse

I had Fibre at Web Africa. When I moved, I called in advance to end my agreement. They said I should call closer to the time otherwise they will switch it off while we still live there. When I called again, I had to pay an extra month because I had to end it a month before. I asked them then to just change my Fibre account to LTE, then I won't loose a months fee. That was the 29th of November. It's two weeks later and I still don't have any form of internet. I've been trying to contact them via e-mail and when I phone them, I have to wait 12 + minutes to actually talk to someone. Their service suck.
