Indian Railways — iam complaining about refund which i did not received till now even after multiple complaints

Address:

East Godavari, Andhra Pradesh, 533106

On 2nd april i did 2 transactions on irctc, transaction id: [protected] and [protected]. Booking of both the transactions are failed and i received a mail that refund has been processed and they gave me refund reference number which are 74506218093000003303641and 74506218093000003303658.

But i did not got refund till now, i contacted sbi customer care, visited branch but they are telling me they don't have my money and they are unable to track and even after repeated complaints on twitter and mails to irctc and minister of indian railways they are just giving me the refund refrence id and not giving my money.
