Charter Club Sheets review: Charter club king extra deep

I bought a set of charter club king extra deep sheets after a few washes the fitted sheet started to rip. I paid close to. 200 for the set that didn't even last a year. I bought it at Macys. Looking inside the fitted there is a line of missing thread and I guessed it started to rip there. For such expensive set this should not be happening. I also noticed there are a lot of complaints about the same problem.
