REFUSAL TO REPLACE LOST LAPTOO

My laptop's keypad was faulty and I took it back to Jeffreys Bay (20 km's). As my wife was still working there I did not wait for any documents. A few days later they phoned me to collect. I found that it was not mine. My laptop was nowhere to be found. They blamed rhe stock clerk of negligence. A RFC ( Return for credit) was issued. One Friday the store phoned that the Area Manager waz on her way from Despatch with a new laptop. She had me waiting tilk nearly 5 o'clock that afternoon. The Manager came and told me that she would be in Jeffreys Bay the following day and that I had to come back the next day. She never came. She informed the manager that I had to bring an affidavit ( SAPS) to prove that I was telling the truth and that I never got my laptop back. After numerous stock clerks and numerous managers and many trips to Jeffreys Bay I still do not have another laptop. I even sent Jish Doore's head office an E -Mail. They never responded. I need my laptop for my work as Engineering Design Educator. Please help.
