Poor Service!

i went into Autopage Westwood in Nov to do a long overdue upgrade.the lasy that helped me did the changes to the contract and said it would only come into effect in December. on saturday the 12th Dec my cellphones mobile data, airtime and bis all stopped working. on monday i called the call centre about 3 times, and was told everything is fine on their side - yet i still had no services. on wednesday i went to an autopage branch- the guy at the shop was equally baffled but couldnt do anything- its now 6days without any means of contact- with Autopage being clueless as to how to fix this problem. it is the 17th(the date when the upgrade is supposed to go through) and i get an sms to say i have airtime, yet still 0MB of data and ) sms's, this is pathetic from Autopage and i demand compensation for a week of no mobile services!
