Bad service

This is no happening for the second time, My mother upgrade her package for the rugby and when she do the downgrade using the online WhatsApp service than they say they will do the downgrade and boom on the 7th of the next month they disconnect dstv and than she have to pay for this ****ty service. Why offering WhatsApp service if they don't do their jobs and than my mother have to phone to rectify the stupid stuff that they cannot fix from WhatsApp. Will never recommend dstv for anyone that's the reason why they losing so many customer because of that poor service they giving they customers.
