What am I paying for

I was debited R285.26 for an unactivated subscription with MWEB. I still have my adsl with TELKOM as I can never get through to someone to cancel that account. I was called by a 3rd Party sales division around about the 18th June and opted to switch to MWEB, was emailed and sms a username, however I needed to cancel my current account with TELKOM before i could just switch. I explained this to the sales consultant and advised that once I've cancelled Telkom I will call MWEB to activate my account. I simply ignored the email and sms with username as I figured I will activate only once my Telkom is cancelled. Now when I call billings at MWEB they dont want to refund me as they say I pay for subscription not usage. BUT THEN WHAT AM I PAYING MWEB FOR? If I already paying Telkom. My emails also go unanswered :( Im rather staying with Telkom
