A-Z Industrial Supplies

Approximately 9-**-13 I was called by someone from Premium Products. I was told that they had a superior diesel additive that would be good to run in my truck engine. I said I would take one gallon at the price of $147 and did receive it. After testing my mileage and performance I did not see any improvement like I was told there would be. I kept getting more calls and was told that I had to pay for a total of 4 gallons even though I did not want any more. I did receive the other 3 gallons. On 10-**-13 I was billed an additional $529 for the remaining order that I didn't remember making. Since then I have put my number on the do not call list and have still had endless calls. I tell them that I don't want any more and they keep calling and calling. I block their numbers and they call from new numbers. I have filed a complaint with the FTC.
