account on hold

I am so tired of the poor service from Heita customer care. They blocked my phone saying I am a bad payer but when I asked for proof they couldn't answer me and still tell me that my account is up to date. My debit order goes of clockwise every month and then they just suspend my account. I cant received phone calls,sms,social networks. Its now a week I cant use my phone so what is the point of having a contract phone if i cant even use it. What am i paying for??? Once this contract expires I will never renew it again. I spend 15 min on the phone on Friday(31/07) and Saturday(01/08) I had to take my phone in to Springs branch because I could not be assisted on Friday. You can take my money immediate when i get paid but when I query something it takes a whole week to sort out. This is BS.
