Greenstone Toys R are rude and unfriendly

Toys R Us in Greenstone is full of terrible attitude. Had to do a few exchanges, some items bought online and some in store. All items exclusive to Toys r Us apart from one. Took 1 hour of terrible attitude from the workers there. They can’t find the slip of the one item on the system which is strange as it was bought with cash at their store - but we misplaced the slip- and they refused to exchange that as they couldn’t find it on their system. It’s not even that that is upsetting, but to be met with such attitude and comments because we were trying to exchange items (for a gift voucher so we can go to the Toys r Us that has stock of the item we want) is unacceptable. This store, especially one lady who works there, is extremely unfriendly and rude. Told straight it can’t be done as an item was bought online, then suddenly it is able to be done. Refused to check the system for the slip and said it’s impossible, when we know it is possible. Yes we shouldn’t have misplaced the slip- but it felt as though they were purposefully trying to be spiteful because we were exchanging a few items from different slips. Made us feel very uncomfortable and as if we were a burden. Mind you we weren’t asking for cash- just to exchange the items so that we can buy further items at Toys r Us and pay in. Don’t have staff that don’t want to be helpful, makes me want to avoid this store in the future.
