Outsurance claims process

I am frustrated at the service I am receiving from OUTsurance, I suffered 2 loses between December and January, My first claim has not been resolved which was fire damage caused to my gas stove in December. I suffered loss caused by lightning and OUTsurance used a company called VCS to replace my back up system, well my inverter was replaced with a smaller one, with no communication from OUTsurance or there supplier VCS, my lithium battery was also downgraded and when i looked at the specs and followed up, the complaints department just said they supplier cannot return the systems as they have already been mounted. OUTsurance does not return my emails or calls anymore more, from claims advisor to claims manager and now complaints department. Service both the insurer and supplier has left me with a bitter taste as they have literally ****** me. After claiming, they have increased my premium by R700 but are failing to complete my claim.
