Amazon phone number not working in panaji, goa again

Earlier amazon was giving the number of the delivery person, for the last few days, amazon has again started giving the number 91226282444 with an extension.
However in panaji, goa, the domain investor is getting the message, invalid phone, she cannot contact the delivery person on 8 december 2019
The amazon delivery person can come any time from 8.30 am to 6.30 pm in the evening , and people who are living alone in a house, often have to leave the home for different kinds of work like shopping.
So if the phone number is not provided, it is very inconvenient for the domain investor who cannot plan her whole day.
