Critical information hidden from us!

I did a cellphone contract upgrade on the 25th of September 2015 at Altech Autopage in the Pavilion. Due to my previous package no longer being in operation, I had to switch to a new package. The lady that assisted us, advised us that the price would be about R560.00. We have received our latest bill for October and noticed that: 1.) The contract information has not been updated and 2.) The bill came to R792.63. Upon querying this amount the first time we were told that the new contract information and billing would only reflect upon the next invoice we received but that the correct information would reflect on their site. Upon checking the site, we noted that the information had NOT been updated and, when calling a second time, we were then advised that we would be paying the amount of R792.63 for the next four months as there were still four months left on the old contract. <br> <br> We are infuriated as this information was NOT disclosed to us in store BEFORE we made the upgrade. They should have advised us of this happening and asked if we wished to continue with the upgrade or wait!!! <br> <br> I am not happy at all because this is CRITICAL information that should have been brought up!
