Still my account is not sorted out

And so we still have issues with my Vodacom account after I was informed that my account is sorted. My debit order never went off this month although there is more then enough funds available. So yesterday, I went to Vodacom Chatz in N1 City to find out whats the story and why didnt my debit order never went through. The guy from Vodacam Chatz ensured me that my account is up to date. A couple of hours later, 13:35 yesterday to be accect, I got a sms from Vodacom stating that my R14575.66 debit order was returned unpaid. R14575.66 DEBIT ORDER???????? For a phone I returned within a day?????? I never gave permission for that debit order. Who gave Vodacom the right to submit this debit order and for what???? This is a ******** act, theft and **********. What if I had that amount of money in my bank account? At the end of the day, the is attempted theft and if this isnt sorted out within 24 hours, I will be laying ******** charges against Vodacom. This is also bridge of contract and I want all my contracts with Vodacom cancelled immediately.
