After Sale Technical support Dismal

This company has very good upfront basic understanding of how the systems work. The only issue is support, or should i say the lack of effective support. Besides a MINIMUM of 48 hours to respond to support mails , when or if they do respond, they believe they are always dealing with the uninformed consumer from a technical stand point. Their main "only?" support person John will respond in ways to deflect the issue you are complaining about and jump to conclusions yet constantly be proven incorrect. I have had tripping issues lasting 2 s for loadshedding quite often. I further have resolved errors daily of which John admitted he could not see , even though i gave him my login and step by step instruction on how to find the erros he simply said he cannot access and showed my his screen (wrong screen) showing no errors. I have been reaching out to USA for some answers which clearly Smart Energy are not capable of answering nor reasolving and am slowly getting answers that Smart Energy could not give. Thed USA has agreed with a question about best practice which John said was not necessary. It is a pity Smart Energy lack of support is letting them down as my interaction with them all the way to installation was really professional. You will see by the response they give to this mail how nothing is their fault and they do everything right
