Is this just a Cox billing mistake or Starz promo ripoff

Did anyone else have this problem -

You may want to monitor the Startz promotion practices, could our experiences be typical of others who agree to the 99 cents for 6 month CANCEL-ANYTIME TRIAL offer?  We cancelled the trial Starz in March,  2 months ahead of time for the trial to end, and received 92 cents credit for the next bill however the next month's bill we lost $10 of the $20 bundled discount we had had from when we started Cox many years earlier,  I called about this and Emily at 3900-4340 gave us a $27 credit and put our "bundle" back into the $115 pre-tax charge we had a few months before. The April bill came with a $109 early termination fee for the trial service of Starz, now Chris in Oklahoma has credited it for next month. This billing should be better coordinated, I'm left wondering if there be something new for June.
