MISLEADING CREDIT PROVIDER

This company suggested I pay way more than my outstanding balance in order to buy a certain product to make up the difference from the credit allocation. The money has not reflected, because the product is no longer available I advised them to refund the different and they agreed. This was 7 working days ago, I have called in every day since then and each day a different customer service agent says it will take 24-48 hours to reflect. This is unprofessional and ********* service to receive from a credit provider. The agents advise me they will call me back with feedback but days has passed and I still got nothing from them. I tried the customer service call centre and the emails but still no response. I would not recommend Mobicred as a company to apply for credit with.
