Discovery Card Miles

Charging me for Discovery Miles option on my Discovery Card, more than Discovery Miles earned in 1 year made me decide to cancel my Discovery Miles option with Discovery. On the day I cancelled the Discovery Miles on my card, it was said that the current amount on my Miles is R407.80 and that I would still be able to use that, as I accumulated that before they charged me for the new year (of this I made sure, as that R407.80 is MINE). Yesterday I checked on the website and I still had 4078 Miles on my account and thought I will quickly phone to find out how I can use that as I wanted to buy a small gift. I phoned and the guy I spoke to explained that there is R407.80 available for me to use (nothing said about reactivating my Vitality or my Miles, and that I can just go online and buy the gift). I decided I'm just going to wait till this morning to buy the Item. This morning when I logged into Discovery again, suddenly it is not showing the 4078 Miles on my profile anymore, but a message indicating "Only active Vitality policy holders can use miles" which was not there yesterday... I've earned my miles throughout the year it was active, and no suddenly R407.80 is just gone? Phoning this morning, I was told that I have to re-activate if I want to use the R407.80, and yesterday I could just use it... Please listen to your recordings of all 3 times I phoned in and let me know if I'm in the wrong here!!! Please can Discovery pay me my R407.80 and close my credit card account as I will not be using Discovery Card anymore!!!
