Indian Railway Catering & Tourism Corporation [IRCTC] — changed my mobile from indian mobile to foreign in error, lost everything (wallet money +ability to book trains)

Since no adequate information is provided in IRCTC, I mistakenly changed my mobile from Indian to Singapore (am a foreign citizen RESIDING PERMANENTLY in India, have OCI). ( As an Indian resident, I should have remained with my Indian mobile number and not changed to Foreign mobile number)

IRCTC site does not clearly tell you who should do what for registering?
1) Indian passport holders who are NRI
2) Foreign citizens who hold OCI but stay abroad
3) Foreign citizens who hold OCI, BUT RESIDENTS OF INDIA ( like me)
4) NRI becoming Non-NRI ( change Foreign mobile number to Indian mobile number)
5) Foreigner becoming Indian citizen or full time resident ( change Foreign mobile number to Indian mobile number)

By this one move, I LOST everything:

1) the Money in IRCTC wallet (Rs 10, 000) registered under my Indian mobile number :This was no more accessible.

2) No longer possible to do train reservations for self, I was always routed to GROUP BOOKINGS only? WHY ? The above happened about 1-2 months ago.

3) I again tried today, IRCTC website asked me to validate my foreign mobile number: I tried to do this some 8-10 times over 45 minutes, but always UNSUCCESSFUL and I have given up. After looking at this complaint site, I understand that this has been a long pending problem, with no resolution in sight.

4) As a permanent Indian Resident in India, I want to go back to using my Indian mobile instead of landing in this huge mess, where I have lost my Rs10, 000 in the wallet tied to my Indian number.

5) I am STUCK now as I cannot book my railway tickets, nor get back my Rs 10, 000 stuck in the wallet !!!

Is there any help possible?

Thanks in advance .
