false advertising by Dstv box office

Dstv box office keeps on advertising that it's available for rentals but yet they know for a fact that the majority of their customers are not able to rent the movies. The above fact is not communicated to the Dstv customers until, I have to call over and over again staying on hold for over half an hour in each instance, all this because the customer service agents are not made aware of this fact, only the senior staff that eventually communicated it to me having had this problem since June this year. The problem of which they say was caused by the system upgrade, yet we pay Dstv for box office access which is not available or working since June 2015. And Dstv does not even post out a notification of the existing issues with the Box office in order to save us airtime enquiring the unresolvable issues that are already known to them.
