Meter installation

They came to our complex to check if the water meter can be installed without hiccups. The other sections of the complex did not cater well for the meter We paid them 31000 as deposit and continue paying monthly instalments They want to refund 5000 and making this a complex issue while they did not do proper inspections. The meter were charging us ridiculous fees which the water was not lasting more than a day Please do not business with them They are ****mers
