Google updating website index slowly to save money?

In an attempt to reduce expenses, google has reduced the frequency of updating the index to a very great extent. In October 2015, the index would be updated in 3 days time and new websites would be included. In january february 2016, the google index period was increased to 5 days. In March 2016, the index is not updated in 15 days. For example the google index is still showing Wallet shopping as a directory of a domain name, though the domain name has been moved elsewhere.
Records show that the google index for wallet shopping was updated on March 9, 2016, and it has not been updated to reflect the change in the name server for the website. Has anyone else observed the same problem?
