No Response from info@nupower.co.za

NuPower Solar no response on aftersales maintenance work request. I think this company might have closed down as i have sent them details of the repairs required on the 2 solar geysers they have installed for me in the past. All information was mailed to them 4 June'25, and resent a number of times to info@nupower.co.za and pierre@nupower.co.za as well as to lynn@nupower.co.za without any response to date. I would like to know if there is another company that is working on their equipment that can assist in the repairs required.
