Purchase not showing on the system

<p>Greetings, I purchased an office chair end november/early december 2016 from the Makro store in bloemfontein. They said it had a 6 month warranty. Yesterday I took it back since the hydraulic system doesnt work anymore. I supp**** them with my Makro card. After a few minutes they told me the purchase does not show up on the system. I told them that it is impossible, I even told them exactly what was bought with the chair, but they couldnt find the transaction.</p> <p> </p> <p> Now I am stuck with this chair that is still under warranty, after they told me I do not need keep the proof of purchase since everything is on record tied to my makro card. I contacted customer support today and I could not make any progress. </p> <p> </p> <p>Help on this matter would be dearly appreciated.</p> <p>My makro card no is - 2 ********** </p>
