Leaking Secure-lid on Nissan

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