@spmajumder We do have an option to delete them! You need to swipe them to the left. (Yes, not many know this - We’re changing that 
)
Currently, if you make a payment without adding the payee, you will not be able to delete it. Only added payees can be deleted. We are changing that so that users will be able to delete any payee.
We’re revamping the whole payments tab and experience. Let us know what you think should be changed! Check this out - Payment tab gets a revamp 🛠️
