Validation required in the Support Us page.

-**Is your feature request related to a problem? Please describe.**
In Contact Us page validation is required in the city, address, name for character length, and contact number for phone number validation in its field.
I can use formik for adding the validation and can do the simple approach also.

-**Describe the solution you'd like**
In this form, I will add the validation for character length for the name, city, address, country, etc.
and in the contact field, I will add the phone number validation.

-**Describe alternatives you've considered**
As an alternative, we can give at least validation in the contact number field.

-**Additional context**
