Thieving DSTV

I received an Email saying if I reconnect by 31March I will only pay R350 for 1 months subscription. I paid on the 28th and was reconnected. On the 6th April I was disconnected again. When I called I was told it was for March as the billing date is 1April, the offer was was from 1 March for 1 month. I said the ad said "pay by 31 March and get 1 month free". I was told its no longer valid as its a new month and it was "pro rata" for March. I explained I paid the full R350 and not a pro rata rate. This is one of the reasons I won't be re-activating my subscription. *******.
