Irctc — difference of fare due to traveled in lower class

Address:

Kolkata, West Bengal

I have purchased ticket in AC 2 tier for travelling from coimbatore to Shalimar. Journey date was 8th June'15. Train No, 12659 & PNR no. [protected]. But ticket was shifted from 2 tier to 3 tier due to that particular date there was no 2 tier coach in train. I have filed TDR on 8th June'15 & it was rejected on 18 th June'15 & again the TDR was opened in 19th June'15. I have already couriered original refund certificate which was given by TTE at train. But till date I have not recd. differential amount from IRCTC. I have continuously follow up the matter with IRCTC, but result is nil. Requested to arrange to refund differential amount in my account. Thanks P Mukherjee
