I called my credit card company and was forwarded to the dispute manager. She asked what steps had I taken to contact the vendor along with what time frame they promised delivery of the product. As posted here 4 calls and 2 e-mails. She said with this diligence, along with the expected delivery date of Sept 25th it would be reason enough to file a dispute with the vendors bank. Which they are now processing.
She also asked specifically whether I had asked to cancel the order in any of messages, which I had. Otherwise another call would need to placed to Penstar to do so. Why the cancellation request to trigger the dispute process I don't know.
It will be within one billing cycle of my card to hear back from the C.C. company and in the mean time I was not responsible for the charge or interest charges incurred on the charge.
If the part happens to show up I can either accept it or send it back with documentation from the shipper that it indeed was sent back, and let my C.C. company know of the choice I had made.
Pretty simple if it goes as she described..... End of story..... I hope.
