Sim Swap Attack | Change Mobile Number

Hello everyone,

I am a Niyo DCB user. I don’t have a credit card but only use their debit card.

Recently, there was a SIM swap attack on my number and a duplicate sim was issued by the fraudsters. Luckily, I came to know in time and was able to save myself.

After this, I changed my mobile number, changed in Aadhar and bank accounts as well as DCB account. But Niyo (not DCB) is not changing my number and everytime I mail them, they ask me to contact DCB (who have already changed the number).

For logging in to Niyo, I need to use the old number which was attacked. Due to this, I am being forced to use the old number. What should I do? Why is Niyo not changing my number which is a very simple things to do for any bank or fintech?
