Don't trust wand makers

Few months ago I found one wand maker (I can't share his information) but he is in Europe and young,he sold me my first wand ( according to him it made with real wood and real magical core from MAGICAL creatures) after i received my wand I was trying to cast the first spell and it didn't work ( Lumos) so you know that I am Muggle born but magical,I had my Letter and invitation in astral world,my situation is very complicated and not know why different than other magical students,any way after working with his wand my life went up and down..few psychic readers told me wand maker put spell on the wand to make your life miserable and definitely out of jealousy,now I know why really I couldn't cast spell and be successful in my casting!!! right now the only way I can trust is to enter diagon alley and buy my real wand from famous wand maker !!
