one department too lazy to contact another

This is a copy of a mail I received from one dept. I spend about R5k a month. I have now asked them for Mr Shameel Joosub's, number after 3 follow up emails. I have never heard from them again. I have told them on numerous occasions that they are hopeless and that I would like to pay what I owe them and walk away. They refuse. Imagine a customer that hates you but you still try and keep them. Abysmal. Dear customer, Unfortunately we are not permitted to send an email to Customer Care on your behalf, as you receive an email with a unique reference number, which enables you to follow up on your email address change. By submitting your request directly to Vodacom's Customer Care, a contact centre consultant will respond to your query within 12 - 24 hours. Kind regards, Ebilling Support
