Vodafone — Unprofessional customer service

Address:

Tamil Nadu

In the month of December, I called up Vodafone customer service for an e-mail address where I can send my request to change my corporate plan to Rs99.00. The CS agent provided me an e-mail address (vodafonecare.[protected]@vodafone.com) where I've been sending e-mails without a response to my request. Lately, I came to know thru another agent that the correct e-mail address is corpcare.[protected]@vodafone.com. When I asked Vodafone how they are going to adjust my billing given that I was paying a higher rental after my initial request, and given the fact that it was their error, the Relationship Manager said that they need evidence that their CS had given me the wrong e-mail address. She was asking me for the phone number and the name of the agent who gave me the incorrect e-mail address in December. How on earth am I supposed to remember the number and name of the person with whom I spoke 2 months back? Should they not be keeping a track of what I spoke with them in December? It's a basic protocol of a CS department to keep a note of the interactions they've with their customers on phone. Please advise - Am I responsible to keep track of the name of the person with whom I spoke 3 months back? Is it not Vodafone who should be saving these details when I spoke to them in December?
