Call centre and account status updates

I am paying for a service to let me know what my account status is every day, sms's which I do not receive anymore but still pays for. Then in one evening I receive 20 of these sms's through the night which is unacceptable as we have a 2 week old baby to get to sleep. Then when I phone the call center for answers, nobody who is equipped to do so (according to the attendant) are present. I am living om a farm, always struggling with your signal (which I pay for), struggling with services (which I pay for) and then struggling with call centre attendants is unacceptable. What am I paying for then?
