Bad quality product

i did my nails at bio beauty for the first time just over three weeks ago - the the****** did it quite neatly and did not rush at all, but after the second day the acrylic started lifting - this is not normal for acrylic as it should hold for at least 4 - 6 weeks. i contacted them and they offered to re-do my nails. so i went and spent another two hours of my time so they could do it over. another week has passed and it looks as if my nails has not seen a salon in ages. it lifts up completely and looks horrible from everything that gets stuck under the acrylic - not to mention the damage that gets done to the nails. i was told that they use the best products on the market - this is highly unlikely. needless to say, i will not be going back there.
