Frank Stack parts geek refuses to give me my core refunds credit. new jersey internet

I ordered a complete brake system from parts geek.com When i recieved my parts, One of the brake calipers only had half of the parts. So i sent 1 brake caliper back  i had to pay $20 return shipping, then they charged me a 15% re stocking fee. I did recieve my refund FOR 1 brake caliper and core minus 15% re stocking fee.

So i had to order a new caliper to replace the one they sent with half the parts. Now i have 2 brake calipers that need to be sent back for core refund. So i sent both calipers back to the tune of 25 dollars for both. they then deducted the 15% restocking fee.

I contacted parts geek about this and they said they would send my core refund 3 different times. It has been 5 months and nothing at all except excusses from them.

So to wrap up everthing up i paid for,

$20) for return shipping for a part that was incomplete then they deducted 15% of  for re stocking it.

$25) for return shipping for 2 calipers minus 15 % re stockin fee

 So now im owed for 2 core refunds of a total of  83.00 total and they said three times we are sendind it and it never comes it has been 5 months and nothing.
