L'oreal — About Hair color

I went for hair color at Loreal salon at Parel ... So when I had called them n explained abt how I want color to he done .. so they told me I ll be charged 5300/- over all including taxes n gst n all .. after I booked my appointment n went to salon over there Ms. UMA quoted me 7500/- after telling her tht I spoke to lady over the call n she quoted me 5300/- still after so much negotiating she charged me 7000/- in which I had asked for global with balayage n she offered me free hair cut ... So, finally my hair color did not come out so well n it's definitely not global with balayage neither they did hair could for me. So my over all experienced was very very bad at Loreal.. rather I would have preferred other salon were they quoted me 5500/- inclusive of everything.
The staff was not tht friendly Ms. UMA espcially was not ready to accept n listen to me. Ms. Soni was not of much help. I preferred loreal because of their brand name n service but I was not at all happy. I did not get wat was promised n it wasted my money n way to expensive.
