ANGRY AND FRUSTRATED - MTN DOES NOT VALUE CUSTOMERS...!!!!!!!!!!

I AM EXTREMELY ****ED OFF AND FRUSTRATED - FIFTH DAY OF THE MONTH, MTN MONTHLY DATA NOT LOADED. I HAVE MADE PAYMENT TO MTN STORE ON THE 28TH OF FEB TO OBVIOUSLY RECEIVE DATA FROM THE 01 OF MARCH. TILL THIS DATE NOTHING HAS BEEN LOADED, NO COMMUNICATION AND THEY ARE REFUSING TO GIVE ME A REFUND SO I CAN GO ELSE WHERE. I AM WORKING FROM HOME, THEREFORE I AM UNABLE TO WORK AS I DO NOT HAVE DATA!!!!!! WHAT DO I DO???...!!!!!!!!!!!!!!!!!!!! I WANT MY MONEY BACK SO I CAN GO TO A NETWORK PROVIDER THAT WILL VALUE ME AS A CUSTOMER!!!!!!!!!!!
