We paid the advance amount for booking of the flat in the month of March 2024 Rs.1lac and another flat in the month of April 2024 Rs.1lac through online transaction. At the time of booking builder told to us will start the project in the month of May 2024. I asked to the builder in the month of May 2024 when the work will be start and builder told to us in the month of June again June month also not started ,next again builder said July then July also not started . Finally in the month of July ending I was given the cancellation of two flats (advance amount Rs.2lacs) and requesting to refund the amount. At that time Marketing Manager told to us it will take atlesst 30days to 45days of time will get your amount. After 45days again I asked to the marketing manager and he said it will some time but not telling the date. One day I went to the office and met Director explained to him each & every situation. Director told to us not to contact to Markeing Manager please come down to the office is on Septmener 25th 2024 will give the total amount . On septmber 25th I went to the office but Director not available . On Septmber 26th again I went to the office and met Director he said will give in 10days , so continously Director told to us will give but not sending the amount. Please help me out this situation.
