Makro Customer service disgrace

Stood in a queue (not the first time at this store) for 45 mins to return an item. One lady assisting. Eventually got to the counter greeted the lady, who did at least grunt a reply at me. Then gave her the item with the original tags etc. She goes off for a few minutes then comes back and says you only have 30 days to return an item. Pushes the item back at me. I said but it is unused. She agreed but sorry cant be returned. I left the returns department saw a security guard gave him the item. One smiling face. Then into the store to buy a few things. Get to the queue to pay and some lady pushes past me to the next cashier. i say to the supervisor, that lady just pushed past me,. She smiled as if to say too bad what you going to do about it. Makro when you first opened your cornubia store it was great but sadly your lack of training your staff on customer relations will not see me going back there in a hurry.
