CUSTOMER CARE CALLS NOT ANSWERED FOR 2 WEEKS!!!!

I UPGRADED MY CONTRACT 2 WEEKS AGO, I HAVE NOT BEEN ABLE GET AN ANSWER FROM MTN'S HEADOFFICE AND CUSTOMER CARE TO GET INSURANCE ON MY PHONE! I HAVE BEEN WALKING AROUND WITH AN UNISURED PHONE AND IF SOMETHING WERE TO HAPPEN I WOULD BE LIABLE FOR ALL COSTS AND STILL PAY MY MONTHLY CONTRACT FEE. MTN HAS BEEN 'EXPERIENCING HIGH CALL VOLUMES' FOR THE PAST 2 MONTHS STRAIGHT, I THINK IT'S JUST AN EXCUSE TO AVOID TAKING CUSTOMER CALLS. I AM FED UP OF LISTENING TO THEIR HIDEOUS SONG WHILST WAITING FOR AN ANSWER FOR OVER 40 MINUTES AT A TIME! <br> <br> POOR CUSTOMER SERVICE AS PER USUAL AND AS A PAYING CUSTOMER THIS IS INFURIATING!
