Sbi's new irctc sbi credit card has been a big pain for the new customers. The third party executives pestered for a very long period to take up the irctc sbi card. After having had the conversation, the very next day one of the executive walked to my office and completed the formality. After a couple of days they started to pester me to send my existing hdfc card details to get approval for my new card.
It was very unprofessional to insist the customer to send the hdfc details as images through whatsapp. Further, the executives pestered me for add-ons like accident coversage policy etc. However i clearly told them, i'm not interested.
So after a month now, i have a standing due of rs. 1500+, mind you i have not used a single rupee from the allowed credit. I have called the customer care many a times to cancel/deactivate my card.
Now, there is no show by your executives, dear sbi. However, they are literally after one's life before selling the product. Kindly revert back and cancel my account.
