As a new new subscriber to the Medicare part D drug coverage I had been ordering a very expensive medication through their "preferred mail order pharmacy". After several months with no problems they sent a bill for a significant amount several weeks AFTER the monthly order was: placed, received, and paid for with a credit card. Their phone response to my inquiry was that the price had increased between the time of order and shipment (about 2 days). I checked with the manufacturer and that was not true, although retailers can charge what ever they want! (read "whatever they can get away with") I don't know about every state but here it is called "bait & switch" which is illegal. I told them no less that 5 times to send me a written explanation which they never did. Strangely, the billing for the following months was at the original price. After 4 months of them sending the same bill they resorted to charging the amount to my credit card. This, of course, is unconscionable, unethical, and ILLEGAL! In every phone call (which I made sure they were recording) I pointed out that if they did that I would take legal action. (Obviously I had the credit card company put the matter in dispute and remove the charge.) About 4 weeks after I sent a strongly worded letter as a precursor to legal action I got a call on my machine that they were canceling the charge. BUYER BEWARE! These people are either crooks or idiots. (It goes without saying that I am no longer a client).
