No, that's sufficient.
If your address is 1CLhAYLHooaWBje969FoPytmyyHtMBg9WT and the funding transaction is 2508f218db9663057bc863f6d986eb84fe8a96f31c61e681847c327dcfce503a, you are the proud owner of output 0, 0.01771605 BTC, worth $45.09 at the time the sender created the transaction.

If he claimed to have sent over $500, i would conclude there is a high probability you were scammed.

Since bitcoin is pseudo-anonymous, and at this point, the transaction can not be cancelled (it's confirmed and has ~60 confirmations), there are only a couple things you could do:

• contact the sender, explain to him that he only sent 0.01771605 instead of the ~0.2 BTC you were expecting
• don't send any physical goods, cut off any service you're providing him untill he rectifies the situation (if possible)
• create a proper scam accusation. If the sender is concerned about continue doing business and/or his/her good name, he/she might rectify the situation... At very least, other people will have been warned about him/her if he/she doesn't rectify anything
