Mweb will take your money with no service!!!

I signed up for a contract on the 4th October. A router was delivered to my place and after so many calls to mweb for the fiber Box, I have been pushed from pillar to post on how they have escalated my issue and how they will credit my account. Guess what, come 1 November, they debited my account again for a service they haven't completed. It's now the 11th of November, no fiber box and no assistance. I have called so many times, put on hold and the line cuts, with no decency of calling me back. I want to cancel this contract and get a refund but it seems their call center is stringing me along. First time customer with this provider and they are useless when it comes to customer satisfaction. Please can someone from Management call me back. I have left messages to no avail.
