Amazon India — kyc document pickup not done after repeated attempts

Address:

Online, 500032

I have been trying to schedule the (Rbi mandate) kyc document pick up repeatedly from amazon and their preferred vendor karvy in hyderabad.
Every time they’ve missed the appointment and now they want me to reschedule the appointment for the 3rd or 4th time.
How can i trust a vendor to handle my documentation when they cannot even keep up their appointment or their commitments? I think they have acted in a very irresponsible way and this issue needs to be handled at the highest level possible particularly because this is a government and reserve bank of india mandate.
