I had my booking via fab hotel on 4th may 2019 in hotel silver crest, vimannagar-pune and when went to check inn the hotel executive told that there is no rooms available and had allotted room to some other. As i had pre - paid already for booking but he refused me saying no rooms available. I was so exhausted, i need to search a different hotel at mid night.
The customer care also dint respond. I already raised my complaint 2 times and not even got my refund back.
So poor and worse service by fab hotel. I am really disappointed by this type of company and want to take some legal action so that any other person should not suffer the same i had.
