Terrible Wifi and customer service at Webafrica

Very disappointed at Webafrica - After 2 years with them, I had to ask for a cancellation of our Fibre line because they were charging us for a 20/20Mbps Fibre line what most ISPs charge for a 50/50Mbps Fibre line. They offered to retain us by increasing our speed, matching other ISPs fee and getting a free month but we have had terrible Wifi since (didn't even reach 5Mbps on certain days) and very bad customer service. I have therefore asked to cancel again but we now need to pay for April as we cancelled our previous cancellation... This is unacceptable and I don't understand how they are still getting business by providing such terrible Wifi and customer service. Definitely don't recommend.
