On 10/8/08 I returned an unused, unwanted shipment to Hydroderm charged to my credit card of $84.00 plus S/H, plus tax, total $97.37. The postal confirmation tracking number says the product was delivered on 10/10/08 to their address. prior to returning product, I called a few times for an RMA#. Their answer "the system is Down" every time. When I asked why so, no response, some said "reconstruction". They told me return and write order ID NO. on the package which I did.Oct. 23, 2008 I called again. Got hung up, called again. the "rep" doesn't know what happened to the package and that corporate would call me on Oct. 24, 2008, I doubt that. Still no refund after 2 weeks after receiving the package. What can I do? Can I sue?
