I have a complain about The Treat at Westgate Mall

I have a complain about The Treat at Westgate Mall. I did my nails there on the 16th of April and they're chipping the gel pilled off from 1 of the nails. I wnt back there today so that they can fix my nails and was told that I they only fix if a client comes back within 7 days. However, when I asked as to how long do their nails last for they said 1 month contrary to their 1 week rule. It's hardly 2 weeks since I did my nails yet they refused to fix them.
