Not returning money on date promised

Really frustrated with hotel express. More than two weeks ago my wife got a letter from them saying that they would reimburse us our finds of R3490 in two weeks - after a complete mess in handling our membership registration. It has been more than two weeks and the money has not been returned. <br> <br> When we called them this week they indicated that they have challenges with their finance department and have not committed to a date when our funds will be paid. I even sent an email to their admin lady - the one who sent us the letter - telling her that we will take further action if the issue is not resolved. She didn't even have the decency to answer back.<br> <br> I am exploring taking this complaint to the ombudsman.
