My dd payments are collected on the 26th of every month. Last month payment was made on the 27th(Monday). Which means no payments are made over the weekends. Its an error on Samsung behalf for requesting the payment on Sunday. I will wait till tomorrow to see if the payment is taken. If not the I will call them.
@B12UMMY my payment is 26th as well it's varied every month depending on weekends as you mention never has a problem so far. My bank says money going out tomorrow ie 27th. Same will wait till tomorrow as their offices seems closed today. Thanks for confirming anyway....
