Conflicting information

I am currently on a Talk200 package which gives me R200 airtime each month to use as I see fit. I am due for an upgrade and went to Cavendish Cellucity where I was told if I changed packages to a uChoose as the Talk packages are being phased out, I would not lose my airtime balance. I took the brochure and as they didnt have stock of the phone i wanted, I went to the Kenilworth branch who told me because the per minute charges were different my airtime balance would be forfeited. So my complaint is two fold<br> a) conflicting information from shop staff<br> b) i don't see how a change in package in terms of per minute costs can affect the absolute rand value of my airtime. I understand that minutes can be forfeited due to different billing values, but don't see why rand value can't be retained as it is vodacom's choice to phase out my contract, not mine.<br> Please could someone contact me to give the correct information because at this point I don't know who to believe,
