Poor client service

Had my nails done and not even a week later they broke and came off... went and complained and they redid the nails that were broken then not even two days later they broke again went in for a complimentary soak off and was told I would get a voucher for that amount or my money back they couldn't get hold of their manager so they said she would phone still waiting for that call.... I eventually got hold of the manager she was so rude and shouting on the phone saying they will not give me a voucher nor my money back..... extremely disappointed
