Dishonored service provider

Installed solar, no CoC (Certificate of Compliance) was issued and earth leakage totally disconnected. This CoC are required by law. Followed up with the office but totally ignored me and no electrician to rectify the faults caused by the installer This company needs to be reported to ECASA, (electrical contractors association of South Africa). Quotation was made for different products than these that were installed, and some of the items on the quotation was not presented.
