Complaint Review: National Express

I called 1-800-741-8183 to order a Water Jet from a TV advertisement.  The call was completely automated.  I answered YES to ordering a water jet and yes to adding a second water jet free with only the shipping cost.  I answered "No Thank You"  for Soap Dispenser and Foam Brush, and answered NO to all other offers.  This is all recorded.  At the end of the call, I was told what my total dollar amount was, and I was totally shocked.  I tried to press zero, pound sign, and *, but nothing would take me to a person.  I tried to call back, but there was no option to correct the error. No Thank you sounds nothing like YES!!!!  I received the item I did not order prior to the items I ordered.  The package had been opened and obviously returned from someone else that had returned it.  I have pictures of it.   They will let me return it, but will not credit the shipping charges for the item I did not order, and they want me to send it back to them via UPS with insurance !!!  I am totally appalled!  There is no phone number you can call to talk to a real person, nor any information on their website information where you can report a problem.
