Billing - Router

I took out a WebAfrica Month to Month service, cancelled it within 5 days (Policy is actually 7 NO ONE told me btw) anyway I cancelled it due ****ty network when the Sales Person said I would get between 10 Mbps and 60 Mbps. I was informed that i would only be billed R220 and i said cool, I can do that but the Monday after and extra deduction comes off my account which equates to R550 which is your monthly deduction and then after i get confirmation it is cancelled you guys STILL do another R550 deduction.Eventually the service is cancelled and the my money is refunded. Now I get an invoice for a router and the only comms i got was the router needs to be returned, no specifics on you guys collecting it or me returning it. The lady confirmed with me now that YOU guys do not collect routers and this rule has been in effect since July.
