I think I lost items / gold from AH

Dear GM,

I am an alliance druid and my name is Adanran. Today I bid a pendulum of doom, and I think that I didn’t receive the gold back from ah when someone bid more for this item. Today morning I still have about 300 golds and now only have 80 in my bag. It is pretty strange and I really want to make sure did I truly receive my gold back from ah. I don’t have any add ons to check, so I may need your help. Thank you so much!
