Hi sampatjay
welcome to the Apple Community.
Re: Apple Pay Account restricted without any reason
The "Related Article" above your question says:
"Reviews take up to 2 business days. When the review is complete your account will either be active, or there'll be a message on your Apple Cash card with your account status".
So, maybe the review is still in progress and there'll be a message.

Re: they will continue with the restriction with giving me any specific reason
The article also says:
"Your account may be restricted:
✽ if your identity verification fails multiple times,
✽ if there are multiple accounts tied to the same social security number,
or
✽ if there's suspected fraud on the account".
So your account is likely restricted for one of those reasons.

Re: "Please help unlock my account."
Article says: "To prevent fraud, ensure account security, and comply with regulations, your Apple Cash account may be restricted or locked".
Although we'd like to help, we are all Apple users, like yourself, in this Community, so no-one here has access to your accounts or details. The restriction may be for your own protection ... we do not know.
All the best :-)
