Crown does not match my other teeth. What can I do to fix this with no insurance? (Photo)

I had a chipped tooth that I wanted fixed. My dentist told me a crown was my best option. Porcelain. The first one turned blue and did not fit my bite. Long story short I have had this crown replaced 4 times and it is still discolored and not the right shape. I have recently lost my job therefor have lost my dental coverage. I’m scared if I go back to this dentist she will just mess it up again and I will have to go thru pain and suffering again. What can I do to fix this with no insurance?
