VODACOM CONTRACT CANCELLED BUT STILL BEING BILLED

i had a contract with vodacom and cancelled it the beginning of the year, due to billing for data that i never used and never got any proof there of. today i call them only to find out the contract isnt cancelled and i have to pay an amount of R2096.36 as the contract is still active only my number is deleted from the network, yet someone else has the number. there service is pathetic and i refuse to pay the amount owing as i cancelled the contract and had a payment arrangement of R202.12 to pay per month which should be ending November as the consultant whom cancelled the contract gave me an amount of R1800 and some cents is what i need to pay wen cancelling the contract and that's when we put a payment arrangment in place. i need to sort this out asap as im not paying another cent to vodacom unless this mess is sorted out. i will never ever recomend anyone to take a contract with you guys your service is PATHETIC, im not paying any more money to vodacom until my account is sorted... im not leavin it lyk this im taking it further.
