Hornbach Reviews

Mitt svenska är inte så bra så jag skriver på engelsk.
If I could give you 0 stars I would.!
I wrote an e-mail regarding this last wednesday and still haven’t got a response.
Last wednesday (29. Maj) I went to your shop in Arlöv with my mother-in-law. We needed to buy some mosaik for my bathroom which we desperately needed for the handymen who is installing Them the next morning.
We brought a piece of the mosaik from home and talked to an employee before entering the store, that it was ok for us to bring it so we could match the color.
We Got 4 things and go to the selfservice cashiers. A Young girl (Nelly) is on duty there and helps us scanning one of the items as it fails when we try. She is not excactly friendly and we could feel she kept an eye on us. We scan the 4 items, pay with creditcard and leave the store and go to the car.
We put the items in the back and gets in to hit the road. My mother-in-law sees then Nelly and a securityguard come running out of the store when she points at us. The guard comes very fast over to our car and tells us to get out of the car and follow him together with the stuff we just bought. As we need to go to another store for tiles, as I didn’t get a match with any of your tiles, I tell him we are in a hurry. He then lets us stay at the car and demands to see the receipt. He gets the receipt and emidiately states that we have only paid for 3 items in the store But have 4 in the car. I tell him that the tiles were from home and we were allowed to take Them into the store by one of the employees. He says, (again) that we only have paid for 3 things and points to the receipt. I now points at the receipt and tell him that one of the lines states “2 styck x 99,00” and to the other 2 lines so that makes 4! Instead of admitting his mistake he then checks the 4 items is correct - which they are!!!
When he realises this he just says ok everything is fine and have a nice day.
WHAT? We don’t get an apology for just accusing us of stealing?? Storming out of the store and to our car for everyone watching thinking that we stole?
We don’t get an apology from neither him OR Nelly who clearly is the one that told the guard.
This was my first and absolutely last time in your store!
So much for customer service??
