KREEPY KRAULY renegades on guarantee and ignoring requests for help

I bought a Kreepy Kraly Dominator for more than R3500 5 months ago. The unit worked perfectly for 3 months, then started "slipping" and not moving around the pool. I sent it back, had to buy new rubber for the wheels, which lasted less than 1 month. I contacted Kreepy Krauly on messenger, after 3 weeks of my constant messaging asking for help, got a message from a LAUREN last night, promising to contact me by 8am this morning. Needless to say, SHE has not contacted me yet and I still have no resolve for my expensive useless faulty product!
