Toni And Guy — I was not provided with proper bill and got cheated

I recently visited Tony and Guy in Anna nagar. asking for a bridal makeover for my sister. They had asked me to give 5000 as advance to book the date . ( Money given on 3 rdof June) .function is on 13 of June. they called us for trial make up on 9 the June. we went there and post trial make up we don't like it personally and so we had to cancel for the function. when asked for the advance back they told 4000 is the charge for trial make up ( were as it was told earlier trial is 1500 ) .when we enquired other stores they still told 1500 rs only . We accepted that and they returned 1000 today. We asked for bill but they dint give any . finally they wrote a hand written bill ( disclosed). this bill was suppose to be for the supplier.
