Bosch TPS Auto electrical complaint

Has anyone ever received feedback from these Bosch guys in Klipfontein Witbank, trading as TPS auto electrical? I wrote two emails pertaining to the complaint I have, they never even responded not even an acknowledgement email le. Clearly this white lady is rude because she is protected since I never received no response after I have sent an email. Before I escalate this further, has anyone ever receive a response from them?
