Incompetence all around

I have tried changing my bank details where my debit order goes off THREE times already. Yet each month Vodacom still debit my old bank account, causing me to go into arrears. The second month they suspended my service because i did not make provision for the funds in my old account. They feel nothing, refuse to accept responsibility and unwilling to help.

I have gone into the Vodashop twice and filled out forms, i have phoned the accounts deptartment to change it? What other means are there?

Terrible, terrible attitude and service. I have no such issues with my Telkom mobile account.
