With all the recent offers of 1000mi/$1000 spent per month for 16 months, I decided to give the retentions line a call today.
Voila - got the exact same thing, AND the $95 statement credit as well

I only had the card open since September (~3 months) so wasn't expecting the $95 credit.
The conversation was smooth - I told them I wanted to cancel since I was earning 1.25x miles with another card (*wood). And they asked if I was spending over $1,000 a month on that card and I told them 'easily' (I do MS a bit).
I genuinely thanked them for the offer and told them how much better the Platinum MC was, compared to AMEX now :P
