Swiggy — Unable to login with my register number

Website: Swiggy.in

I am unable to login to swiggy application with my registered mobile number [protected]

Getting an error message as a mobile number has already been used in the last 6 months.

All my payment methods are registered with this number and I have tried uninstalling and reinstalling swiggy app and even I have performed factory data reset on my phone still the issue is same

Requesting you to please fix it as early as possible.
