Is this crown mess up? Can I ask for refund? (Photo)

had a root canal & crown done 1st crown had to be redone because a gap at the margin. This 2nd crown is the same with a gap but is too short not making contact w/ upper tooth. my bite is off & have pain. Also having issues with liquid & saliva giving me a warm cheek. Saw original dentist today was told my bite it will correct it self. the pain frm headaches have been going on a week. Don't know if he just saying that so he won't have to redo/refund. should go see another doctor to redo crown.
