What is happening????

So I got a reminder that my contract is due for upgrade, naturally i go to inquire about this by the closest store.<br> Firstly, I am looking for an iPad Air. No one had stock in the southern suburbs so I went to Tygervalley. The staff member who was assisting me said yes they had one in stock, he then processed the upgrade and I got the SMS stating that the account is upgraded, we did the paperwork and then he opened the package and i noted something. There is one distinct difference between the iPad Air and Air 2. The Air 2 has a finger print sensor. I told him to double check this and he too found that he was about to give me the Air 2 on the R369pm package. He then told me he cannot upgrade the account because they do not have the iPad Air and that he can lose his job if the auditors find that he sold me the device on the wrong package. He supposedly cancelled the upgrade. I walked out of there with 2GB of data on my sim and under the assumption that the downgrade was completed.<br> I think not! <br> I got an SMS not he 21st of the new month, as I always Do, stating that my account has been credited with 2GB of data? so i am paying R369pm for something i don't have.
