Poor after sales service

Purchased a top of the range zodiac robotic pool cleaner approximately 5/6 years ago. Called today for a repair / service call only to be told that they no longer keep that model and that getting parts would “be a challenge”. 1. When we purchased this very expensive pool cleaner we were not informed that their after sales service would be limited to a few years. 2. After indicating that we would be happy to wait for the parts to come from overseas, I was then told to that I could take the unit into their Sandton branch as they could not do a home visit because the unit is out of warranty. This, despite the fact that I was prepared to pay for a home visit and, moreover, as a 64 year old woman I don’t have the physical strength to pick up a unit this heavy. Unfortunately, unless this unit is repaired we now own a very expensive but useless piece of redundant equipment. Certainly not an experience that leaves one rushing to purchase another zodiac item. I wander if the Spanish parent company feels the same way?
