Vodacom not providing service

I am so disappointed at Vodacom, have a fibre contract with them. Always pay my monthly installment on time, Have been a good customer and i am expecting the same service to be provided. I have app**** for a opportunity that will help me put bread on my table and all i need from Vodacom is to update my latest address on my statement so i can produce to my potential employer. When i called VODACOM I am told they cannot help me i need to wait for 30 days. In my case i cannot wait for that number of days as my application will be withdrawn if i dont produce the statement on time therefore i will loss out on the opportunity.I have emailed *** the manager to assist and the call center agent *** to give me an update on request but i am not receiving any feedback from them. I am sad that i will be missing an opportunity that will change my life because vodacom cannot update my address on my current statement.
