c***** didnt fully compensate

hi. im a small time biscuit manufacturer. i purchased 10 butter from a local store which was very cheap. however the product all flopped when baked. 1st time this has happened. I did complain to the store. they response was no customer ever complained and cannot re-inburse me. i then called c***** and laid a complaint. they were very entertaining , they tested a butter from they factory with the same batch number and nothing was wrong. i then requested that i would buy a butter from that store and send to them to test which i did. the response was that probably the store had it left out too longand wasnt kept at the right temp. so its no fault of c*****s. they gave me a voucher of R500. ive lost 3 staff wages for the day, my flour, icing castor sugar, 11 butter including the 1 i sent to them AND A DAYS production. A big company like c***** shouldve compensated me fully. however i must state that the person concluded was very compasionate and said that was the best she could do.
