*****ulent sales with no certificate which was meant to lower my insurance

Its been hell dealing with this company! They sold me their service but never delivered. Sales person said a fit met certificate would be sent with the installation...didnt happen! i told them ill only pay when i get what was sold and now they have listed me ! please advise which ombuds man can assist me here ? i think i saw their head office in Midrand , the next step will be to go there and it will not be a nice visit . The CPA must come into effect as these ****** sell lies to hook people and they must be stopped. No one has called to investigate this matter they just do as they please and mess up peoples lives.
