Bad service

I am writing this in frustration towards Vodacom. They are quick to hand over client's account to legal companies. I do acknowledge my outstanding debt with them, even though I still believe it was their fault for sending me incorrect statement after my cancellation. I have been called by a legal company regarding this debt and i have requested them several times to send me the account number via email which i can use to make payment in. To date, i still have not received that email with banking details. I have called Vodacom several times to request this banking details but i was advised that they are not able to assist me with the legal company banking details because it's not their bank account. I have advised the Vodacom consultants that i have tried to get hold of the legal company but failed, and consultant said they can't assist with that . The least they can do is transfer my call to the legal company even after i told them that the number doesn't even ring , it just drops . They still transferred my call. I really don't know what do to do now. As this to me comes across like this delay is made intentionally in order for my debt to have more interests /arrears.
