Unacceptable answer.

I did an upgrade on the 07-03-2015 and migrated to a smartchat 2gb.I returned on the 08-03-2015 about 24 hours later and requested to cancell the migration and stay on my old straight up 100 package.I was told at the store it cannot be done and i had to call customer care and they advised me to contact the retentions dept on Monday morning as they were closed.Called and was told that i would recieve a case no,which i never recieved.Called again & finally recieved a case no but was told nothing could be done.MY ISSUE IS AS A LOYAL CELL C CUSTOMER NOBODY COULD ASSIST ME BY JUST CANCELLING THE MIGRATION.I EVEN ASKED TO SPEAK TO A RETENTIONS MANAGER BUT I WAS BRUSHED AWAY.I WAS TOLD I HAVE TO WAIT 3 MNTHS BEFORE THEY COULD CHANGE MY PACKAGE.THIS IS UTTER NONSENSE,ITS LIKE BEING BUL**** INTO THE DEAL.I FIND IT HIGHLY IMPOSSIBLE THAT NO ONE CAN ASSIST IN THIS MATTER.I AM CERTAIN THAT THIS CAN BE REVERSED.I WOULD APPRECIATE SOME HELP IN THIS MATTER.THANK YOU.
