I have requested for payment link for the pre-EMI that I have to pay due for 31st May
And the pre_EMI values that is due for payment is increasing.

I have been requesting the link from 3 weeks

I initially got a link which soon expired (within 1-2 days), thereafter I have put many emails requesting a new link, but not a single executive responded to the mail
There has been no reply since May 16

Not able to submit a request/complaint on the hdfc home loan page also, has some issue with submitting the request
