Discovery do you actually care about your clients?

Why is it that Discovery Card will sms you every time a debit goes through your card but simply refuse to sms you when they debit your card with interest?<br> I believed there was a certain amount in my card which was more than adequate for my purchase only to have it declined.<br> I was mortified and immediately telephoned Discovery to ascertain what the problem was.<br> I was told that interest had been charged to the card 2 days ago.<br> When I asked why I did not receive a sms to that effect I was informed that Discovery do not do that, so basically, tough.<br> I find this asinine and would appreciate an answer to this obvious failing.<br> The statement that this would appear on my statement is not acceptable.<br> I need to know whenever an amount is debited to my account, not days later.<br> Honestly Discovery this is really not rocket science.
