Worst service ever! Blatant disregard for client service.

ismrt - Remote Metering Services - By far the worst company I've ever had to deal with in my entire life!! First of all, my payments seem to magically disappear, unless I harass them, then 4 days later it magically gets allocated to my meter. Power off since 8am, 17 emails, 20 calls, and even a useless WhatsApp conversation later, they still have not allocated the payment made today, so again, no power. I can't believe any company of this magnitude feels f@%£ all for their clients.
