I'm writing a review to hopefully persuade others from making the same mistake as I did, by using Doxo. I ignorantly used the Doxo payment portal to pay my electric and power bill (separate bills and companies.) Both of which were deducted from my checking account, but reported as "invalid account numbers." I then reached out to customer service, who was unfortunately did not have a phone service, and it was incredibly hard to get immediate answers. Needless to say, my bills were both late and it took weeks to be refunded the money. Luckily, I caught the issue in time and was able avoid having a power shut off, unlike some of the other reviews I've read. Please avoid using Doxo.com as it may indeed be a scam. If not, hopefully the company will sort out their issues.
