Terrible customer service !!!

I bought a size 7 shoe and they delivered a size 8, I logged an exchanged they picked up the size 8 and exchanged with a size 8. I logged an exchanged about 3 times and they kept picking up the size 8 and bringing back the size 8 again, I gave up logging an exchange because they exchange will be a size 8 again!!

I don't know what to do with the shoe anymore, it's ridiculous !!!
