Bad service

I have booked and requested a room for 4 people. The request went through and I made payment and received confirmation via email. The day before traveling I phoned the place where I was booked only to my surprise they informed me that I have booked a single person room and not for 4 people as I have requested and they informed me that uf I decide to come and book in I have to pay extra almost double the amount to accommodate 4 people or I should contact Agoda through who I made the booking. I phone Agoda explain to the person who assisted me my situation I am in and I need an solution. They assisted me was really trying his best but the only solution was he cancelled my 1st boking and that I will receive my money in 15-30 days. I am very upset because we had to travel and needed a place to stay and I was told to booked again on my expense with money I do not really have and had to make a way to borrow money to book a room and to travel late. I am really disappointed with the service and the mistake that was made and I had to suffer and make means.
