web africa sucks!!!

so i have mailed them 100 times regarding my internet not working, no responce, then i mailed them to cancel my internet no responce, so i cancel my debit order, now they want to phone me every day i own them money and there is website where i must cancel but there is a mail adres on google to mail them , one day they said 200gb use the next day 300gb and no one as home, they want me to courier the router back and i told them to come and collect it, it was not my choise to cancel they forced me because of bad service or no service.. ***
