Terrible service - again

This is a company that is very quick to sell you their system, but very slow to provide technical support. I have had a problem since Sunday 20 July. On Tuesday the technicians from Sparki came and made the problem even worse. I have had no solar power since Tuesday. Tomorrow is day 8. The call center agent I spoke to is useless. He didn't escalate the problem as requested. I am paying for a service I am not getting. This is the 2nd time I have had an operational problem and the 2nd time I have to resort to this platform. The turnaround time is terrible. A clear breach of the SLA and no way to remedy other than to cancel.
