Hello my name is ***** ***** I will help you.
Did you get proof of posting or send it recorded delivery?Alex
You are correct, its not your fault it was not sent. You sent it and have proof of posting. Unless their terms say it has to be posted in any particular way (ie recorded delivery) then its not your problem.
Can I clarify anything for you about this today please?Alex
If I could invite you to rate my answer before you go today please, otherwise the site does not credit me for the time spent with you today. Thanks and good luck. Alex
