Disgusting Unifi Connect Owner

This business is not even worth half a star because of the owners disgusting manner in which he deals with his customers. So we ordered fibre from him and it was said that payment begins as soon as the installion is complete. that was agreed and we had no problems with that, then a few days later he said our fibre was active and we need to pay so i explained to him that no installion was done so it didnt make sense for me to pay when i didnt recieve any services. He demanded that we pay anyways and then sent my partner will rude aggressive emails trying to bully and threaten us. He is very unprofessional and i will like to advise people against doing business with small over night companies as they are just ****mers. This man Janos truly is a disgusting humanbeing .
