Bad customer services and unfriendly stuff

I went to buy front and rare wheel bearings on Saturday 28/09/2019. The place is so busy that they even forgot to be kind to customers. On receiving the parcels I bought, the only thing I could see was just a code, it didn't say what was inside. I went home and started to work on the car. On double checking now, I saw that the codes are all the same on the boxes and different on the receipt. I had 701 and 702 on the receipt buy physically I only have 702 in all the boxes. I check all the bearings are the same. I went back +_ 15km away to exchanged the bearings. I got there, they looked at the receipt and the bearings and exchanged... no apology at all. They didn't say nothing as if the was nothing wrong. I mean the products were checked and the was a stamp saying they are the right goods for me.. Atleast an apology was going to be something other than the fact that I had to use extra petrol for their mistake and bad customer service. This are the things that makes businesses to loose customers.
