Absolutely horrible lack of service

My contract has expired a few months ago and I am on a month to month contract. I need to upgrade my contract but also in the process change to another pay-as-you-go number.

For some reason Vodacom has been struggling to do this for a month already. How is it possible that you are unable to cancel the one contract and port the other number and start a new contract on that number? Is there a competency issue at vodacom with your staff?

How long am I to wait before you find the time convenient to you to assist with this?
