Below is word for word the email I originally sent them. To my surprise, the next day, a Fedex package was on my doorstep:

"
I have a mesh loop-lock cover which has several holes from wear &
tear. I read somewhere where you have a repair kit that you can mail to
owners.If true, I would greatly appreciate a repair kit. Besides the address
which I include below, please let me know if you need anything else. Thank
you in advance,"

I never had to call. It probably depends on the mood of the person when they read the email.

Good luck
