Having used mobileworks in the past for similar work, I would not recommend them at all. My request was bounced around from worker to worker, nothing was accomplished and they stole my $50 dollars without offering anything in return.
Sorry you had a bad experience! We always cheerily offer refunds or set things right when things don't work. I'm happy to look into this myself -- feel free to get in touch with me directly if for some reason this didn't happen and we can figure out what went wrong.
I submitted a refund request and it was never honored. Just as the work I submitted to my virtual assistant was accepted but never completed.
I considered it a $50 experiment to see if this would work or not, but not receiving the refund when I asked for it leaves me inclined to warn others about the claims being made.
