Hi Greg - no - this is not really acceptable. BUT, we did previously have such a case where a member was extremely unhappy about a warranty issue about a pump..... The thing is - you should try and find a technicality, which you you can use against the supplier.... alternatively, try "hellopeter.com". Or even perhaps try and get the pump's importer details - and contact the importer....
Unfortunately, consumer after sales service is TERRIBLE in South Africa.
I had SUCH A HUGE fight with Chrysler Jeep about my Jeep..... The worst service I have EVER encountered! And this all due to a wire on a speed sensor, which they soldered very badly!
I repaired it myself - after HAVING to pay them R5600.... I was EXTREMELY P|$$3D off!
I won't buy another Jeep again - even though I am relatively happy with mine..... BUT just because of the service!
