Home Warranty of America unprofessional suppliers are sent to homes and charge for nothing Lincolnshire, Illinois Nationwide

We acquired home insurance for our home appliances (two years old upper market brands), one day our microwave started to make a funny noise that we never heard before. We made our first report to call for an engineer, we explained the problem, after the appointment was rescheduled twice finally the engineer came completely unprepared, he didn’t bring insurance of his company required by most NYC buildings. As a result building manager refused to let him do any work or even touch any appliance, without any documentation. We arranged for him at least check the microwave by just listening to the noise, which was very noticeable, he said in a very poor English, (he didn't speak English nor Spanish properly): “I need a new piece that will come in few weeks, but you have to pay me now” We asked “pay you for what?” “if you haven't done anything yet” and he said “it doesn't matter you have to pay just because I came”  We called the supplier company and arranged to pay when he will back with the "piece" and actually repair what’s needed. One day before the new visit (3rd) we received a call from Home Warranty saying that the Supplier informed that our Microwave didn’t have any problem based on the technician "assessment" and that we have to pay the visit fee!  We complained with every person that answered the phone and all of them said it doesn't matter that the appliance hasn't been repaired you have to pay. we will send you another technician but you will also will have to pay for the visit!  at this stage we were so annoyed with the lack of professionalism of the suppliers and the poor customer service of Home Warranty, that we ended paying for nothing and cancelling our insurance losing money on the way and still having the appliance with a problem.
