********** UPGRADE!!!!!!!!!!

I have been trying to have a ********** upgrade from the past month. After numerous calls I make to different departments I was advised it will be escalated and called within 48 hours. However I had to call back after 48 hours expired to follow up and was informed escalation was closed however not actioned. ***. Anyway after that call it was suppose to be was supposed to be called back again and still NOTHING. This morning I have spent over and hour of my time being transferred from pillar to post and still no one can help and NO management available either. I would this issue sorted before my next debit date. So I request that some call me back urgently wrt to my issue.
