Frogfoot refuse to refund me

They Damaged my cable with installation and refuse to refund me after i got it fixed myself. They first deny it and then requested a quotation that i provided from myself they then ask one from the one that did the job i provided it, then he refuse to take that one because that man was subcontracting they wanted from the main company holder and i gave them. they still refuse to except it. because of the company name and the description the company used on the invoice does not state electrical work done. due to that i had to be without electricity and lost my food that i had in the refrigerator. the issue is i have a contract with RSAWEB but frogfoot did the installations of the cable
