Still Account problems!!

I am now sick and tired of struggling with my mother's account. We pay the account each and every month without fail and yet they suspend the account. And every time we need to drive out to Vodacom to sort out problems all because Vodacom can't do their job. Can someone please call me so we can sort this out once and for all. I'm at the point telling my mother to cancel her account with Vodacom and move to MTN. Hopefully they will provide better service
