Paint was not used as specified by me

I hired a painter to paint my house inside and my paint selection was to be BHER , but the painter said he had an account with Porter paint in Murfresboro who could match the paint color we had chosen, the paint was not purchased at porter paint but was Sherwin Williams bought at Lowe's and after repeated attempts to get the painting redone we have yet to get it finished, the painter keeps saying he will make it right but has not as of late. I HAVE THE RECEIPTS FOR THE PAINT HE PURCHASED AT LOWE'S AND I WANT THE WORK TO BE DONE OR I WANT THE $2400 I paid to be refunded to me
