DISAPPOINTMENT WITH GAME STORE

Good Day

I would like to ex[press my disappointment with game store. My husband had opened a Game account and purchased a smart 49" tv last year June 2017. we have been payng and instalment of R1000 a month and have purchased a few times after that s constantly high. payments that was done had not reflectednce of +/-R6000. we then called the customer service agent from the store and he advised that the payment did not reflect and will take a few days to reflect. Early February I called the customer service department and reminded them that we requested a full detailed ledger or statements since the account was opened and did not receive them till then.They had called my husband to confirm as this was his account. we called again telling them that we would not make payment till we get this sorted. thereafter we received statements which was not complete. Now our bill is standing at +/-R8000. which I feel is not correct. I have asked game and customer service to assist but no help again. now we get an sms telling us that the account is overdue and will reflect poorly on our records. who's fault is this ????????????? CAN SOMEONE ASSIST
