An angry client

I'm destraugh about the **** service we receive from multichoice and its agents,firstly we use our airtime to call them on landlines and hold for good 5 minutes for an agent to drop your call n start the process from scratch..I really am very angry with their **** service and still cannot clear the error on my decoder even after several calls for the same ****en thing...next thing they quick to send SMSs of how much one needs to pay each month whereas we spend 2-3 days with an error on my TV.?????
