I upgraded my contact in May.the device lasted 3days n then the charging pin gave up. To date i have been pushed from pillar to post regarding the pick up of the device n i was told that there is a delay.we are now in July and the device has not been picked up. Today i made contact with cell c only to be told that i did not pass the security check bearing in mind that i passed the security check from the day i have been quering the pick up of the device. I have exhaused all means to try and make contact with the technical department. Mr. MTOKOZISI as per our conversation on the 2nd of July u assured ted me that this will be resolved. It is now the 21st of July and nothomg has been done. I WANT URGENT ASSISTANCE PLEASE!!!!!!!!!!!
