Pathetic service from Remote metering solutions

I very disappointed with the service we are getting at remote metering solutions. You call in at the customer service they don't help with anything they are just useless. You send an email in still you don't get any response. Remote metering solutions is really pathetic. My account was over billed from 23 July 2021to 25 July 2021, the reason I noticed this its because I was away over those days but I was billed ridiculously. I'm starting to think that their billed is just a guess work. They just guess on how they going to bill accounts.
