Premium date - doing what they want

I really dont know what is so difficult to understand. Numerous times I have asked that if my premium date falls on a public holiday to deduct afterwards and not earlier. Now my premium has gone off earlier and they took my last money which I was suppose to use to buy the last food for Christmas day as I am only getting paid tomorrow night. So thanks Dialdirect for *****ing me over this Christmas as you keep on doing what you want with my money. I think its time to take my business elsewhere because I am so tired of being treated this way after being a client for so long. I hope the idiot that changed my premium date has a fabulous Christmas as he or she has *****ed mine up because I wont be able to buy the food in time to prepare. Thanks a lot.
