DEVICE DEFRAYED DUE TO LACK OF COMMUNICATION

I HAVE REPORTED ALREADY TO THE CALL CENTRE, TO HELLO PETER AND TO THE STORE ITSELF AND YET I AM STILL GETTING A RUN AROUND. MY BLACKBERRY Z10 WAS TAKEN IN FOR REPAIRS AT SHELLY CENTRE IN OCTOBER 2014 BY STORE SALES REPS WITHOUT ME SIGNING ANY AGGREEMENT, WITHOUT ANYONE EXPLAINING ANY REASONING TO ME ABOUT ANYTHING THYE SAID THEY WOULD CALL ME BACK TO SIGN BUT THEY NEVER DID. EVERY MONTH I CALLED AND QUERIED ABOUT MY PHONE AND I HAD NO FEEDBACK. THE STORE SENT EMAILS TO THE REPAIR DEPARTMENT BUT NO RESPONSE. I GAVE ALTERNATE NUMBER *** AT THE TIME BECAUSE THE PHOEN WENT THROUGH WITH MY SIM CARD. I WAS NEVER CONTACTED ABOUT THE QUOTE ON MY ALTERNATE NUMBER. THE REPAIR DEP CONTACTED ME ON A SIM CARD THAT THEY HAD IN THEIR POSSESSION. IVE BEEN PAYING R400 FOR THIS CONTRACT TO DATE AND AFTER THE STORE TRIED TO HELP GET MY DEVICE BACK I WAS STILL NOT GIVEN BANKING DETAILS UNTIL THE CALL CENTRE GAVE ME DETAILS I PAID THE COURIER FEE BECAUSE THE STORE TOLD ME I HAD TO PAY A LARGE SUM FOR REPAIRS AND I DID NOT WANT TO SO I PAID THE FEE THIS MONTH HOWEVER NOW THEY SAY MY DEVICE IS DEFRAYED AND I SHOULD HAVE KNOWN THIS BUT NO BODY TOLD ME ANYTHING OR HAS MY SIGNATURE ON ANY DOCUMENT.
