Appalling service from Webafrica

Webafrica has to be the most appalling service provider in the country. After waiting for 3 weeks for their technician to come and install the router, I decided to cancel my subscription with them. which I did. I asked them where should I drop the router, they gave me an address which I went to, only to be told when I got there that they had actually moved! I had driven 30 k from work! They agreed to pick up the router from me (this was in October last year). Gave me a date. No one came. Then I got a lawyer's letter demanding that I returned the router. I explained what happened. They agreed to pick up the router. Gave me an exact date. No one came. I queried what happened. They came back to me saying they were querying with the courrier. I then got an invoice for the router and today I found out that they have actually debited my bank account without my permission as I am not a customer of theirs! This is totally unacceptable. And I still do not know when the router will be picked up! I have asked them to reverse the debit order immediately.
