Washing machine vanished

Miway claim C*** I would like to report a claim made to Miway more than a year ago, they took my washing machine off my premises through their respective service provider, the claim was for power surge but they(service provider) claimed my machine issue was not related to my claim and repudiated my claim. Ok that was good and well, I requested for the return of the machine many months ag but to no luck. Recently the sales team phoned me to sell me short term insurance, and I in turn requested my machine back, I was put through to another consultant to assist but little prevailed. I would have fixed the machine myself last year already or bought a new machine if it was not going to be fixable. Now I sit with a predicament of not going to trust their service provider didn’t take my machine parts or swap my parts with other old machines or used my parts to fix other Washing machines. It’s really unacceptable and I can’t go on like this with this matter. MiWay is a big company to be treating this issue in this manner. Otherwise is it my fault their service provider kept my machine over a year? Like really!!! I’ve tried emailing them and voice so now this is my last resort. Please assist
