Finrite refuse to pay out the claim

On 13 July i took my phone in for repairs with Foschini as Finrite administer their insurance on the cellphones. After two weeks i paid R500 for repairs that did not happen. the phone was not fixed upon arrival. Afterwards Finrite send the phone back and forth to Foschini and the phone still was not fixed. Finrite and Foschini now is blaming each other of (a sticker that supposingly was removed) of which i have no idea where the sticker is situated on the phone. Due to this sticker which was apparently removed by I dont know who, Finrite wants me to pay another R500 which i refuse. E-mails are been send between the two parties none of which can come to a conclusion since the phone was declared \beyond economic repair". To date my pnone is in for repairs three months."""
