I want my money back you *******

In August 2018 i went to make a purchase from jet, only to be told my card does not work, The lady at the store Phoenix called the call center and i was informed that my card was reported as ******, which was not the case as i had the card in my possession at the time of purchase. the lady told me that a new card will need to be issued. when i got my statement i see i was charged for a new card. i called jet and inquired they told me that they will credit me the charges and was given a reference number JET REFRENCE: ********** 1292/go . Its now December 2018 and i still have not received my credit for charges which was not even my fault seeing i did not report the card ******. i want my money back you theives.
