Very unappy and frustrated client

I bought a jacket from Markham in River Square on Saturday for my husband as a Father's day present and I paid R750 on my account. My husband took the jacket back today in Vereeniging as it was to small. The lady refunded the jacket and afterwards told him that he can not re-purchase the jacket as it is not his account. She called me and explain to me, I ask her if we will qualify for same discount as it was less 30 on Saturday, she said it will not be allowed, I told her why cant they him him the jacket back and I will return it myself, cause now i paid on my account, got the jacket and now she is telling me to pay more before repurchase and they also cant give him back the jacket. I am very frustrated, feels like I should have just send him without a slip or my card but this happens by being honest.
