no Feedback

so i took out a contract at game stores the 1st of October at Cresta, everything went well etc , a week later i get debited for an amount of R254.00 which i had no idea of!!!! I called the call centre on the 12th of October , spoke to Josh and got a ref 1- ********** 183697. i was told within 4 days i would get feedback! guess what no phone call or a follow up! my account is in minus and i look like a bad payer . do you guys not give your consultants proper training to advise that a payment is needed within 7days ?????? i want a credit of R75.00 in my account because of your *********** staff ! hopefully now i will get feedback and get my issue resolved! Secondly why is your staff not getting back to me as ive left a contact number for him to call me on!!!!
