Suspended,Account Arrears, After Payment Made!!!

I have been a client for 12 years , Vodacom contacts me on the 12/11/2015 in the morning.After arranging that I will settle my account on a certain date, they suspend some of my lines that same evening 16:45,not all? I have 10 contracts costing me - R4000.00 p/m, not much for some people, but to me it is.I had to make a payment 13/11/2015 and done so at about 06:00, these are business and private lines.I had to not make other payments,but who cares?After receiving sms notification:they have received my payment,not all my lines are active and it is now 14/11/2015.I have made about 6-7 phone calls and every person has something different to say.My account also still shows in arrears,WHY DO YOU SEND ME A SMS NOTIFICATION:PAYMENT RECEIVED?Does all your systems run separately or maybe it is incompetence!My son could receive calls, after speaking to Vodacom, THEY MADE IT WORSE, NOW HE CANNOT EVEN RECEIVE CALLS!The only thing they say,is SORRY,I have never not paid my account in 12 years, yes sometimes late, but I have always honoured my payment arrangements.I will never suggest anyone to go to Vodacom, NEVER! But let me guess SORRY. I have voice login, still they ask security questions!!
