We cancelled their service back in November (because they are not in-network for our insurance) and asked them repeatedly to pick up the testing meter. Instead they kept calling us asking why we haven't been calling in our results, and each time we remind them that we cancelled their service and to please take back the testing machine. Now, 5 months later and they send us a bill of over $637 saying they havn't received a payment with in the past 30 days. Hello! We cancelled you over 5 months ago! What a moronic company that has inept customer service!!!!
