Bad attitude and poor service from Accounts department

Vodacom had not debited my account as per the arrangement they require when the contract is concluded. Now i have missed a payment and they had locked both my likes with them. When I phoned to explain and request that my lines be open as i will pay the arearrs amount at month end, the supervisor at the accounts departmentjuat rudely told me the they are not willing to assist. I am aggrieved as I have been a Vodacom contract customer for many years. Absolutely disgusted.
