Indian Railway Catering & Tourism Corporation [IRCTC] — tdr repudiated with 'coach not short'

Address:

560066

I have raised tdr for pnr [protected] but always repudiated. Actually pnr status is changed to 'reld' on chart preparation and unable to get any seat number for this pnr. Then received a new pnr [protected] immediately that was linked to original pnr and that was in lower class so i haven't travelled and filed the tdr on time before 4 hours after departure of traind but every time it's repudiated.
Please advice/help to get refund the money from irctc as they have to cancel the ticket if seats was not available in same class instead providing in lower class and every time original pnr should be given seat number and should not generate new pnr that we can't cancel. It shouldn't be downgraded. Every time repudiated saying 'coach not short'. If coach/seat was available then why not cleared with same pnr as confirmed and why status of original pnr was changed to 'reld' and new pnr with berth number is released on chart preparation.
