Peek-a-boo connection and unwarranted account suspension

The first few months all was well. Had a stable connection. Then it went down hill. The connect takes time to come back after loadshedding. Connection also plays peek-a-boo every other day, one moment it's fine then all of a sudden it's gone then it's fine for a few minutes then gone again. Then there's the suspension of my account when I've had a successful debt order payment that's gone off, where is the sense in that. This has happened more then once. I enquired, got it fixed and after a feed months it's happening again. I've been trying to call in but the line barely rings. Another thing, if you are suspending someone's internet, why are you sending an email instead of an SMS? How is the person supposed to read the email without internet...
