Unfairly Billed

I'm not outraged by the service we have received from Mweb , i'm just confused and quite disappointed. The overall service has been good however someone has some explaining do with the billing. <br> <br> We selected the Uncapped Package. The service was activated in the calendar month of March however we only received the modem in the month of April, therefore as a result we only started using the service in April. We had already complained about the delivery of this modem because it was already 4 weeks since we signed up! <br> <br> We then received the bill and we are expected to pay for the month of March!!! That can't be right because you activated the service but then you didn't give us the modem so how must we pay for a service we never used? <br> <br> Someone needs to be held responsible for this because i refuse to pay for that month. They activated the service without the modem being in our possession. Its like activating the service of a cellphone but you don't even have the cellphone with you!!! <br> <br> Im expecting a response and for someone to resolve this issue.
