Multiple calls a day from this number. Have same phone Samsung Vibrant. Didn't know it had reject feature. Now I know. Way cool Thanks. Problem solved.
I got them to stop calling. I placed a fake order with them (false address, CC, changed last name) and was able to glean that the company that provided US Pharmacy with the leads is MBK Services. I found their number on another blog, called their number 877 914 1412 and left a message, notifying them that they could face a lawsuit.
An individual who said his name was Ralph Smith with the number 408 599 9158 actually called me back! He apologized and said that he would make sure they don't call me back. They have not called back since.
