Issue with webforms

Comment from customer: You will likely have got multiple submissions from me, your webform is not very user friendly, the message field sends the form whenever I hit enter, yet the fields suggests I can put in returns, which will be automatic for a lot of people.

There is also another issue. I have enlarged the comments field so customers can properly type their enquiry. Problem is that the type does not wrap to remain within the box.

I have shared this site with you at https://preview.webflow.com/preview/justcovers?preview=4d2636da74ec3b2dc9df4bbee5e56a7a
