BILLING QUERY

I AM APPALLED BY THE SERVICE I AM GETTING FROM MTN. BEING A CUSTOMER WITH THEM FOR MORE THAN 15 YEARS HAVING HAD SEVERAL CONTRACTS, SOMETIMES 3 AT A TIME. SINCE MY UPGRADE IN MAY 2015 I HAVE IN THE FIRST PLACE BEEN CHARGED FOR DATA USAGE AND SMS WHEREAS I SIGNED AN INCLUSIVE PACKAGE FOR THIS. FOR 3 MONTHS I HAVE BEEN CHARGED AND DEBITED FOR THIS. PHONED AND VISITED THEIR CENTRE SEVERAL TIMES AND ALL I HEAR IS THAT MY QUERY WILL BE ESCALATED!! WHEN THE DATA AND SMS WERE EVENTUALLY REINSTATED THE REFUND TO DUE ME IS ANOTHER BATTLE. ALL I HEAR IS MY QUERY WILL BE ESCALATED!!! THEY DO NOT HAVE PROBLEM DEBITING YOUR BANK ACCOUNT BUT WHEN IT COMES TO REFUNDS IT IS ANOTHER STORY. I FEEL LIKE MIGRATING TO ANOTHER SERVICE PROVIDER. MTN YOU SUCK!!!!!
