BAD BAD SERVICE

On the 6th April I upgraded my cellphone package. The consultant at the store upgraded the WRONG cellphone number(I have 2 registered to me)and I have been struggling to get it fixed since then. The store says its not something they can fix the call center needs to do it. I didn't expect them to as the consultant wouldn't even get up to get a booklet but rather told me to do it. So I've been calling the call center, holding on to speak to someone for at least 15mins EACH time and EACH time I have been told the query has been escalated. HOW DOES IT TAKE 5MINS TO MAKE THE MISTAKE BUT A MONTH TO FIX IT??? BAFFLES MY FREAKING BRAIN! I don't want reference numbers for my calls, I just want the package to be reversed to what its supposed to be. I still have over 500 characters left to complain about the disgusting service of the consultants as well as the supervisor - but what's the point? While there is so much sad things going on the world that I would like be paying more attention to - I have to deal with the pathetic service I am receiving from a service provider I have been loyal to for so many years. Best believe once its sorted, this contract will be cancelled!!
