Indian Railways — ticket not booked but money deducted

I booked 2 tickets for mumbai from delhi at 3/11/2017. Money got deducted from the bank bt ticket not booked. Tried all the customer care no available on irctc site not abel to connect single no. More than 5000 rs deducted from my account and i have no idea about my ticket... What railway expects that all the middle class people should have extra money with them to block... And they should wait for the refund and book another ticket and spend double the money for same thing, we even don't know whether by the time money comes back tickets will be available or not or will it be of the same price... Please help me get my money back and get the tickets booked...
