DISGUSTING SERVICE JUST TO PAY YOUR ACCOUNT

I have a vodacom line which my mom is currently using. I received this contract quite a while ago, and I don't remember the residing address anymore, as I have already moved 3 times since then.I would like to make a manual payment to the account, and when I phone to ask for the banking details and the reference number to make the payment at the bank, then the call centre agent ask me security questions, of which I am told I do not give the correct answer to 2 of them. Because of that, they can not give me the information needed to make a payment. How does that work? When I have answered with my ID number already gave 2 addresses just to be sure where I changed the billing address too. I don't work for vodacom, so how am I suppose to know the package name? I can tell you what you receive on it.When I could not answer the questions as they want me to, all of a sudden....THE PHONE DROPS DEAD IN MY EAR, NOT EVEN A GOOD DAY TO YOU SIR, NOTHING, JUST PLACED DOWN. I do not deserve to be treated with disrespect at all! When vodacom does not receive payment, they cut the line, and DEMAND payment? But vodacom LACKS the systems to assist loyal customers properly to make a payment!
