unbelievably **** service and theft

After paying R59 to activate blackberry Internet service, and receiving an sms confirming the service is active. I was shocked to receive a message on my phone after browsing for a little over an hour that I had no airtime to connect to the Internet. Here is the start of four phone conversations trying to explain what happened only to get told it was my fault because the service was not activated yet. After many aggravating conversations finally success. Or so I thought. I was refunded and told to reactive my bis service. Again I receive a sms confirming the activation of the service. The sms confirmed the expiry date of the service was 9/2/16 because I activated it on the 9/1/16. Unfortunately by the 12/2/16 the service has not yet been activated. After 2 hours of phone calls and being hung up on four time I had had enough. Driven to such a point of hopelessness and anger the phone is no more. I have never seen a company so inconsiderate of their customers.
