Once again Vodacom does not deliver

So I get a message today that I should upgrade as my contract is about to expire. Speed to Vodacom, wasting very precious petrol. Get there, the most helpful ladies. Gives me the most awesome contract. Shows me the devices. Get to the computer to start the upgrade... can only upgrade in 3 months!!! Phone Vodacom, no it was a message for premature upgrade. Speak to upgrades, yes it is premature upgrade, Speed back to Vodacom cause I can have a premature upgrade, whilst talking to Vodacom on the phone to just update this in order to get the upgrade, O no you cannot upgrade now. Only in July!!!!!! Are you freakin serious???? Yes it was a system error. Ok. So why did the other agents not say this. And why did Vodacom not send a 2nd message to confirm the error? So wasted petrol (which is flippen expensive) and lost an awesome contract thanks to Vodacom's error and staff!!!!! I want my upgrade!!! At NO extra cost. This has cost me enough time and money today
