Failure to do annual maintenance

I wrote a review about a year ago commending Wetility for their professional service. Today I’m disappointed to say the least. Our system has been tripping for days now and thank God for Portia, who came to my assistance and took me through the troubleshoot. Now what I am fed up about is the fact that after the many attempts to troubleshoot, the system is still tripping. The one battery does not charge and Wetility has failed to send technicians to do the annual maintenance, regardless of the many times I have called in to request the maintenance. Maintenance should be routine, the same way the debit order goes off every month without a fail. As I’m typing, I am preparing my children for school in the dark. Y’all better do something quick
