Showmax not activated, but getting billed

My parents signed up for Showmax over 3 months ago, and we needed a voucher number to get this activated, which has never been received. Every saturday my father goes into the Telkom store at Lakeside Mall and advises them that they have not received the voucher and that showmax is not activiated. This has been ongoing, and we are always told that the ticket is stuck with technicial and wil be resolved. To date still not resolved, however the latest development is that we are getting billed for a service which we have not activated or cannot use, due to the lack of the voucher number. Cancellation of service is looking like a great option. USELESS!
