Nasional Consumer Commission;A absolute disgrace to the South African Public.!!!!!

Bought a vehicle Audi Q3,2013 model,+-121000.during November 2017 from LisaBank in Fourways, Johannesburg. There were a few items that needed to be fixed by LisaBank and after requesting LisaBank to fix the said items, till today we have not had the slightest response from LisaBank. We had some of the items fixed at our own expense. On 3 April 2018 we took the said vehicle for a service at Audi Fourways. We were contacted by Audi Fourways and informed that the cambelt had not been replaced during the 120000 km (major service). Before signing the purchase documents we specifically enquired whether the vehicle had been serviced according the service book.(cam belt was supposed to be replaced)/ Lisa Cars confirmed that the service was done according to specifications and this fact was also indicated in the service book. The cost involved in replacing this cam belt would have cost me according to a quotation from Audi Fourways about R14000. We contacted Lisabank to enquire why they sold us a vehicle under false pretensions. After contacting LisaBank, they refuse to rectify the problem. We refuse to have the cambelt replaced on our expense as according to the law this was Lisabank responsibility.See the Consumer Protection Act.Sec 55 and 56. We reported our complaint to various institutions, with absolutely no resonse from anyone. We referred this case during AUGUST 2018 to the National Consumer Commision of South Africa in Pretoria. The complaint was appointed to a Miss. Prudence Moilwa to investigate. No correspondence regarding the progress of the case was ever made by Miss Prudence Moilwa. When my wife made enquiries via email regarding the progress of the case Miss P.Moilwa confirmed once by email the fact that she is dealing with the case and that she will returned to us regarding the outcome of the case when she has finalized it. This is now about 5 months later and still no progress or finalization. This complaint is now close 11 mo tonths in the hands of the National Consumer Commission Pretoria and in Miss. Prudence Moilwa's hands. The National Consumer Commission is a public institution and supposed to uphold and look after the public and to serve the public interest as far as consumer rights are concerned. This is clearly not the case in this instance. This institution is an absolute disgrace to the South African public they supposed to serve.They(National Consumer Commission) are of absolute no concern regarding us as the consumer,our rights and seem not keen to perform their work properly or have any regard or respect towards the public,they are supposed to serve .This institution is a clear indication of poor service that we as the public of South Africa have to deal with on a daily basis.One can just wonder how many other complaints are there from the general public regarding the pathetic service this organization provides. Trying to deal with them is a nightmare as you have to communicate through a call centre and have absolutely no chance to speak to the person dealing with your complaint.Request to phone you back is falling on absolute death ears. I have been very patient with the National Consumer Commision but waiting in vain for nearly a year has left me with no alternative but to proceed this path.
