Sorry JG, I misunderstood the question, no offence intended.
Those people at yahoo might ban for no good reason, maybe even some spiteful false report by someone about you.
Of course I don't know what happened about the later attempted correspondence but good luck with that and don't forget if they don't have a satisfactory answer never give up just create a new account. I know you aren't the type to just give in.
Now , what about giving me a promise that you'll have 8 hours sleep each night?
