Back in November I opened for fursuit commissions. Client got a spot, paid the 30% non-refundable downpayment and replied promptly to my emails for three days (11/25 to 11/28). I have not heard back from my client since November 28th, 2017.
Since then, they have sent payments via PayPal for the suit in December and January, effectively and fully paying for the fursuit commission. In the last PayPal payment they put in the notes section that some things came up and they apologized for the lack of communication, yet paid on time.
As of November 28th I have sent them 6 emails, the newest being a few minutes ago, with progress photos and asking them to reply to my emails. Currently the fursuit is halfway done.
In my form I ask people put down their social media in the off chance they do disappear so I can contact them somewhere else; the client put down their FA. I left them a shout 4 days ago asking them to reply to my emails and saw that they had favorited something hours beforehand, when I checked a few minutes ago to see when I had posted the shout their account shows they were active 3 hours ago.
I have an abandon clause in my Terms of Service that states that, if a client is to halt communications, I reserve the right to alter the fursuit and re-sell it so a full refund can be given. As this is an artistic liberty piece designed by me no alterations need to be made but, as stated, it is paid for in full.
Any advice on what to do at this point would be appreciated, I'm very lost and have never had this happen before. Thanks!
