False Info

So I would really like to know how bad Vodacom's service or at least processing of upgrades has gotten. I used the USSD code to check when I am due for an upgrade an on the sms it states that I am due the 29th of June so I call a Vodashop to ask if I am still able to upgrade anytime within the month that states I am due and they advised yes. Now I am not blaming the vodashop I am blaming the person that processed my previous upgrade. I want my upgrade as when I previously upgrade I took a handset that the agent advised is a nice phone and I have never had a handset that gives me so many problems so I was very excited to upgrade just to be told no sorry you can only upgrade 04/07 then I need to wait to hear if vodacom will allow me to upgrade earlier than 5 months and I need to pay additional fees on top of the contract price for I guess 5 months. paying for a handset that is terrible and having to wait just makes me infuriatingly mad
