Yesterday, I was promised 15 months at half the price of the 12 month rate ($89.95 for 15 months). The woman (I think from the Philippines) told me at least 5 times it was for 15 months, and I was still skeptical. So when confirmation email showed I was billed $89.95 for 12 months instead of 15, I was so perturbed I called today to cancel all 3 receivers. The exceptionally nice and professional woman, Kathy, at customer service instead offered me the $25 for 6 months, which I took. Then she said I was just billed $108 for 6 months on my home unit, for which I never received any email. She said that was way too high so said she'd give me the same $25 for 6 months on that unit. Lastly, she said the woman who lied to me yesterday had also posted a note at the top of my file in all capos, 'NO MORE DISCOUNTS', which Kathy removed.
Kathy is solely responsible for retaining me. If I'm ever lied to again as I was yesterday, I'll drop them for good. That is, unless I get to speak with a person like Kathy again. In hindsight, $50 (plus tax & royalties) for 12 months of XM split evenly between 2 receivers is the best deal going.
