I have been requesting and submitting update requests to refrain any communication on my old mobile number. The bank executives and call centers just shake their heads like dumbasses but none of them are listening and/or updating. The guys are so busy marketing personal loans and gathering customers for dumb investments like mutual funds but they do not have time to update customer details.
I think more calls to the old mobile number should now be taken to consumer court and reported as Do Not Call violations.
I have reported this incident to Financial Services via CpGrams DEABD/E/2016/04416
