I'm sorry that I couldn't reply sooner. I'll be happy to help you with these five problems.
It's not clear if you still want to use the email option or not, since you have posted the problems already. I'll send you the Additional Services offer just in case though. If you no longer want to use email, you can simply reject the offer, in which case I can post the solutions here on the page.

Hi Ryan,
Can you please close and delete this request. Things somehow got goofed up.
I will open a new request for assistance on different items later. Thanks and my apologies.

Ok, no problem. I'll send a note to Customer Service to close this one.
