Kreepy Krauly Dominator

I bought a Kreepy Krauly Dominator on the 12th September 2019 for R2299.00, it worked fine until May 2020. I noticed that the kreepy krauly was not cleaning the entire pool but just going in circles in the same spot. My husband removed it to check if any debris or stones may have gotten into the device but there was nothing preventing it from working properly. My purchase was made at Makro Riversands in Johannesburg. The telephone numbers listed is never answered, so I take the device in on 6th July 2020. I was told that they will get the supplier to have a look & get back to me. I didn't hear from them so around the 26th July I popped into the store to check on the progress, I was told that I should wait for 21 working days before I get feedback. I was rather annoyed & left. I received an sms a few days after I went in to say that the equipment has been sent for assessment (30/7/2020). A week later I get an sms to say that I must approve a quote to repair the item. No amount is quoted on the sms, so I go into the store on 12th August 2020 only to be told that the Dominator gear levers are damaged and the cost to repair it is R780.85. I then say to the customer service agent that this should be covered in the guarantee/warranty. She called the supplier and from what I understood is that the chemicals from the pool has damaged this & its not covered by the guarantee. I've had other Keepy Krauly Dominator & it lasted for at least 3-4 years, with the same hth we put into the pool, so I'm baffled. I request the agent to send an email to the store Manager & copy me on as I'm not satisfied with the explanation. She assisted in getting the email sent to the relevant people but I've not had any response. I responded to her email stating that the Manager Chantelle get back to me but to no avail. I attempted phoning Makro on17th August 2020, no answer. I'm hoping you can assist me, would be most grateful to get a resolution. Kind regards Priscilla Pillay
