FRASTRATED

Yesterday i created an online profile and paid the amount due on my account which was 2839.00, later received an sms from mdb that i am handed over, when i call truworths they said i must send proof of payment they will update my account, they havent done that, i am receiiving calls from MBD They telling me i still owe 300 while an agent from truworths told me i olny owe R3, I AM GETTING VERY FRASTRATED NOW
