thanks, hope you have a good one too. 

I didnt mean to act as though I was shouting. 

I was getting frustrated because I hate spending a large amount of time on returns that should theoretically be easy, but get derailed due to stupid things like this. 

Like someone else said, I put about as much effort into the return as the client themselves is willing to put - once the amount of time exceeds that which the fee can justify, and the client is not willing to pay more, I consider myself done. 

Thats why I am not bothering to dive further into this. If he has trouble with the refund later and needs my help, he can pay me more at that point.
