Just had a letter from BT, explaining that all though I managed to get a reduction out of them on reregistering, next month they will give me the difference between the new value and the current Option 3 for the remaider of the 12 months and then I revert to full price.
Yea I had this same thing happen; 'your discount will appear as a credit' for the 12 months. I'm assuming that after the 12 month contract period I can once again go through the haggle procedure. It does appear underhand and definitely a tiresome procedure to have to go through every 12 months.
Wouldn't it be something if BT actually started valuing their returning customers!
