I have a tax problem- H& R Block keep messing up ( as so often)?

I hired Block to review return. They call it COMPLEX and already gave 2 different refund amount after I complained. I came up with $ 249- Here are the numbers. W2- Box 1 $7200/ B2 $960 -retirement plan sickpay taxable-1099 MISC - Box 7- 8910 ( expenses 3783)SSA-1099 box 5 14939 - Trust K-1 - 1041- Box 1- $480 - 2a $6970 - 2b 2632 - 14- B $109- US Gov int. on line 1 -$117- total income foreign countries $ 1075 - foreign taxes $ 109- Block tells me they do not credit the foreign taxes!!! I always got them credited. They seriously asked me to give them a list of countries to where I paid taxes!? You are supposed to write other countries. I know $ 100 more or less is not much. It is just that I hired Block to do it right and they did not ! I paid them not to prepare my return but to review it - I came up with a refund of $ 249. Any tax professional out there who is smarter than Block? How can I argue with them that I get tax credit? "Professional" hung up on me!!! What a service.
