PAYING FOR SERVICE WHICH WAS NEVER RECEIVED

WARNING - DONT EVER USE WEBAFRICA

I requested an internet line on the 25th January but when I did not hear back from them, I had a line installed by another company at the begining of February. When this line was installed, I started to get SMS messages from Webafrica telling me that the would be delivering a router. I called to cancel the line but the courier still arrived. I refused to sign and accept the router as it was no longer needed.

Since then, my bank account was debited twice and I had to pay my bank in order to reverse these charges. I have also been on calls to Webafrica and sopken to 10 agents since then in order to cancel this account. Today is the 24th May and I am still struggling to no avail.

What do I need to do in order to cancel this account and have them reverse the charges. I have no intention to pay for a service which I have NEVER received.
