Warranty Not Honoured - No Feedback

The disc of my Genius pool cleaner has degraded and broken to a point of non-usability. The warranty period is still in force, and does not explicitly exclude such events.<br> During e-mail correspondence with Zodiac, there seemed to be some good co-operation. We agreed on a service centre where I could drop the damaged part off, for Zodiac to collect and assess. Now, more than 2 weeks later, I have had no response let alone any hopes for a working pool cleaner in the near future. Every day that goes by without it sends my pool into worse condition, making the rectification process more and more difficult and costly.<br> I expect a replaced part, since it is covered by warranty- no misuse/abuse, etc. And I expect it quickly- better service- I need it urgently.
