90MIN ON HOLD

I UNDERSTAND THAT THERE ARE CHANGES IN PROCESS, I UNDERSTAND THAT A CUSTOMER SERVICE ENVIRONMENT CAN GET BUSY, BUT FOR ME TO HOLD ON TODAY FOR 90MIN AND MY WIFE FOR 20MIN TO EVENTUALLY BE TOLD I CAN NOT BE CONTACTED BACK. THIS IS UNACCEPTABLE AS I SPENT ALL MY NEW MONTH FREE MINUTES AS WELL AS ADDITIONAL AIRTIME ON HOLD AND STILL DIDNT NOT RECIEVE ANY ASSISTANCE. AS I SAID I UNDERSTAND, BUT FOR AN HOUR AND A HALF????NO COMPANY SHOULD OPERATE IF THIS IS WHAT IS REQUIRED FROM THEIR CLIENTS. WE USE CELL PHONES AND HOW CAN IT WORK OUT THIS EXPENSIVE TO RECIEVE SERVICE. I DEMAND THAT I BE CONTACT BACK ASAP!!!!!
