Vodacom useless

I’m still getting the your accounts in arrears automated call from Vodacom. I payed the amount the first time but the calls continues every day. Spoke to vodacom billing dept this weekend the lady told me I wasn’t in arrears that I was payed up. Just went to Vodacom head office in George now and they wanted me to speak to a consultant who is working from home. But she couldn’t help me because her system is down or something. Good service Vodacom George. I wish I could get out of this contract I’ve had enough now.
