Refund on rings not received

In June 2015 I bought 3 Eternity Rings, but they were too small. I was told in the store that they could be resized to fit. I had to pay the R29 000.00. The First time I went to collect the rings only one of the three fitted. They were sent back so that the other two could be resized as they were not resized the first time. Again, after receiving the second call, the lady ensured me that the rings are back again ready for collection. I arrived at the store and the same two rings were still not resized. I was not happy and I completed a refund request form. After 2 weeks the money was not refunded. I called the store and Sheryl did a follow up and informed me that the R29 000.00 wil be in my account the following day. 2 Days later the refund was still not done. Christine at client services informed me that the bosses are not in the office to sign off the permission for the refund to take place, but promised that it would be done on Friday, 9 June 2015. Needless to say the transfer was still not done and this morning Tracey at Centurion Mall promised to get back to me which off course did not happen. Will never do any business with Brown's Diamonds again!!
