Frogfoot still a tadpole waiting to be eaten by a fish

You recently came to install a box at my house and never bothered to connect it correctly and so no username or passwords given to me work. I responded four times since Saturday when you resent me my username and password which does not work yet you have not bothered to respond. I have given you all methods to get hold of me. This is unacceptable that I have to pay for such appalling service. It will be greatly appreciated if you could follow up and actually do your job properly
