Dishonest Staff

In December my mom's TV packed up and a new TV was needed - An employee at the time liaised with her sister Jasmine Scheepers who is an employee of the JD Group. Jasmine offered to purchase a tv on my behalf in order to qualify for a discount. I transferred an amount of R5050.00 on 11th December 2015 to Jasmine's account for the transaction to be processed. I was then advised that the TV ordered by myself (Hisense) was out of stock. just before Christmas 20th December 2015 I requested a refund as this inconvenience would be too great and i would rather just walk into a store and purchase a TV immediately. Jasmine said that she would get back to me regarding the procedure for a refund as she needed to liaise with her Manager. On the 1st January 2016 I followed up and was promised to receive my refund asap. I am now unable to get hold of Jasmine and I am furious!!! What is the procedure i follow to receive my monies and also am curious is this the integrity and honesty that your company displays through their staff??
