SUSPENDED LINE DUE TO WRONG ACCOUNT ALLOCATED

I would like to get help with my contract thats been suspended without my knowledge. I got a call from one of the sales consultants offering me a double line contract of a Samsung A10 & a Samsung A2 core going for R344.00 per month. I took the contract and provided Vodacom with all details that they had requested that including CORRECT banking details. To my surprise i just got an SMS stating that my lines were suspended due to non-payment. To my surprise i had provide Vodacom with a Capitec Bank account number and now i am being told that they couldn't allocate funds from my FNB Account which i dont have. I am now being told that i need to pay R1411.40 to have my account activated because i have penalty fees. WHO GAVE VODACOM AN FNB ACCOUNT? I will not be held accountable for a debit order that i have provided the right details with. I would like to be contacted regarding this matter ASAP
