Stop Harassing me!

I have had my bond with ABSA since about 2007, and have been paying it diligently every single month. Not one payment missed. Now lately, I get SMS reminders to pay my home loan by the due date. Why on earth do they want to annoy me like this? Surely they can chase the people that don't pay and leave the people that stick to their commitments in peace. Surely these SMS's are coming at a price too - wasting money I would call it!!! Stop harassing me please!
