Flying Machine — Product tag is unmatched

Address:

US4070 SERILINGAMPLY

I bought the product style as FMJNO1183( which costs around 2199 when I check online) but the tag they attached to it was FMJNO1634(which costs around 2399), which means for less value product they billed the higher amount. I wanted to replace but the store is not allowed and is very disappointed. Kindly help how to replace it.
