Why is it?

Why is it that when I buy stocks using an online trading service, money is instantly deducted from my account, but when I sell stocks using the same service, I will get money after two working days?

Why is it that when there is a false transaction in my telephone/credit card/travel bill and I raise a dispute, I have to pay first and then prove that the transaction is false and then if proven, expect the refund in some weeks?

Why is it that when I purchase something using my credit card, the dues on my card go up immediately, but when I make an online payment, it would take 2-3 days for the “transaction to reflect” in the balance?

Why is it that when I use a prepaid service (shopping card, mobile phone) and the company has deducted an elephantine sum from my balance, I have no way of talking to a human in the company about this?

And after all this, why am I being given the sugar-pill that I, being the customer, am a King, and am most important to these large corporations running these businesses?

Is the individual so downtrodden and helpless in this corporation-led economy?
