The vendor Changed their name BETWEEN beginning the service, when we paid half, and the end of the service. Then we got a bill for the second half from a company we didn't recognize. We contacted our service person, and learned he was no longer with the company, but this was the company we should pay. Then, we get 3 calls, 2 on the same day, asking for payment. We really don't want any further contact with this disorganized rude company.
