Baracuda Zodiac
Service not what it was

I am the (previously proud) owner of a 2-year old Baracuda Zodiav MX8.
I wrote two roaring compliments because the MX8 goes where NO OTHER poolcleaner goes. It never sticks.
But alas now, after 2 years, I need help and the numbers I had don't work. Norman, the tech.'s Cell is not on. The Tech.-helpline: no answer.
MY PROBLEM: The "tractor belts (Item 17) don't turn on the one side. I figure it's the little gear connecting (item 18 on the diagram), but I can't make contact. I bought new tractor belts, bit no improvement.
I'd love to turn this complaint into a compliment again (as it was), but the contact is missing.
I don't mind PAYING for such a repair, or even a service exchange (that should be available).
Jes, of course I'm in anhurry!
Come on, Baracuda, show me you still want to service to be able to sell in future.
Regards,
Conroy Marais.
