Indusind Bank — Request for Reversal of Incorrect Joining fees of Signature Credit Card

Address: 11th Floor, Tower 1, One India Bulls Centre, Jupiter Mills Compound, 841, S.B. Marg, Elphinstone Road (West), Mumbai – 400013

I received a call from IndusInd bank representatives. During the conversation, I was offered an upgrade from my current Aura Edge credit card to a Signature legend credit card, with the assurance that the upgrade would only incur a nominal fee of 500 rupees.

Having considered the benefits of the Signature credit card, I provided my consent for the upgrade. Upon receiving the upgraded credit card, I noticed that my account had been debited with 5000 rupees instead of the agreed-upon 500 rupees.
So, I'm requesting to revert back that joining charges. I do not need Signature legend credit card.
