Pathetic service.

I am a vodacom contract client, having at least 5 of them and I've been attempting to cancel 2 of expired contracts regrettably I was told my account is in arrears, ofwhich previously they debited R4100 from my bank account and later I was advised by vodacom to go to my bank to do a stop payment as they have wrongly debited my account for that amount and they further suggested I should make straight payments onwards, I have been honouring the payments eversince the day I was told to make straight payments. I've been patiently waiting for a call from Admin since May 2015 as I was told by vodacom agent that my account has been escalated, to date nothing has materialized. Bearing in mind im currently aligible for an upgrade on all my contracts but now im having second thoughts about vodacom whereby they make it difficult for me to cancel two of my contracts as they claim my account is in arrears thats the reason I cant cancel ofwhich its untrue my accounts are all up to date. My concern is a negative reflection on my personal profile at ITC (credit bureau). For the past 5 months I hzve been waiting for a call unfortunately im still waiting, been calling them on weekly basis.
