Leaking Securi-lid on Nissan

I bought a new Nissan NP200 in May 2019 from DTM Nissan George and they fit a securi-lid at LA Sport. The lid was leaking and I took it back to LA Sport in George in October 2019. The lid was still leaking and I complained to Nissan, who organised to send it back to LA Sport for reparation after the lock down period, which was on 5 June. The lid is still leaking. The complained was send to Nissan,(johan@dtmgeorge.co.za) newbusiness@dtmnissan.co.za), the Distributors (info@ezicover.co.za), the Manufacturers (info@securi-lid.co.za). Nissan replied that they are not responsible, because only let it fit by somebody else. The Distributors replied that Nissan is aware that these lids leak, "but don't grant them to seal the top for draining purposes". The Manufacturers did not reply. The problem still exists, but nobody is willing to accept responsibility and I am aware, as the Distributors, of other people with the same problem. Gerhard
