Metro Prepaid Terrible Service/Metro Prepaid Must Fall

Terrible after sales support with Prepaid water meters. I purchased a prepaid water meter 4 weeks ago from one of Metro Prepaid's(MP) distributors. Had a qualified plumber install the meter. When purchasing tokens the Meter is in the minus at all times. Have been contacting Metro Prepaid for assistance, everytime they have different stories, 1. The meter was installed incorrectly, facing the incorrect way(I send them proof that the meter is positioned correctly). 2. MP suggest I install a release valve.(Why do I need to install the release valve if the installation manual doesn't instruct me to) 3. MP suggest I need to wall mount the meter. (again their installation manual does not instruct any of this). The meter is on the same water line as the council meter. I've asked them to send out their field tech/plumbers to investigate what the issue is, every agent has a different story, 1 said they will escalate to a GM, the other says they have logged a request for a Tech to go to the property and investigate, the other says they do not have a plumbers in the field. Its been 4 weeks now, they have not resolved anything or taken ownership of the issue. I was considering to install these meters in 3 of my properties but this is a no go, I wouldn't recommend this to any landlord.
