Indian Railway Catering & Tourism Corporation [IRCTC] — tickets booked after 10 minutes resulting in waiting list

Address:

Kolkata, West Bengal

I was trying to book tatkal and went till the payment options through paytm but after going round and round for sometime i got error that transaction could not be completed as my bank couldn't confirm the payment and by this time all the tatkal tickets was booked so i didn't try again. After 10 minutes i got sms and email saying that the ticket with pnr [protected] has been booked with waiting list number 30 but i didn't wanted that and ultimately had to cancel it and ended up paying 60 rs cancellation which i think is ridiculous.
I then complained to irctc about it but they wouldn't care and got a very rude answer that charge will apply if ticket cancelled but my original complaint is why the ticket was booked after it failed on first attempt
I need resolution for this and want my 60 rs back.
