Refund issued for $10.52
Refund was showing in my account for couple of days, then it became zero. They say i have withdrawn this amount. But i was never asked and never given my bank account details to club factory, how can they claim that they have transferred the amount to me.
Whole system does not look logical. This way they are cheating customers with refund money.
