Flipkart does not even give an option to change the Mobile no from the previous updated in account to new number. When the old mobile number no more valid with us flipkart does not give us an facility to change the number to new without having access to older number or either entering an alternate number in the profile.
Due to which flipkart customer care executive itself is unable get in touch with us also we couldn't make use of Filpkart Pay later option until and unless we provide OTP sent to the old mobile number which is no more available with us.
Flipkart has to find out some sort of solution to this and betterment there customer service.
