National Board Of Examination — Failed transaction for neet mds

I tried to complete my online payment and registration of mds 2021-21 but the transactions failed to help line number anywhere provided not even in the NEET website . there should be an other ways of registration if in such case opting for only one way is an inconvenience if failing multiple transactions. i request to accept these transaction and complete our registrations in order not to loose our hard work and time as today is the last day of payment .
