Agree with OAP. However, I do love the "Dear Sirs, or Frank" ... that subtle insult is well done; the rest of the letter just sad.
if you want to see stuff like that go read the reviews of gambling apps on the apple App Store (I'm sure they are as nutty on the Android store but I haven't checked)
OH MAN! Frank is outing all of my sock puppets! Now I have to invent all new sock puppets! THANKS FRANK!
