Awful service.

I called on 1/13/15 to renew my loyalty discount for another 2 years (a customer since 2001).  I was given a new rate of $215.00 for the next 2 years.  I received my February bill of $215, and paid it on time.  On March 4, I receive an email that my bill will be going up to $267.50 as of that date.  I called to inquire about my contact from 1/13, and they had no record.  I explained I still have the email and already paid one bill.  After an hour speaking with someone who had no clue on what was going on, he updated my account, and now it is up to $274!!!  WTF.

I have called back several times and no one wants to help with this issue.  Asked for a supervisor more than once and was told none are working.  What gives?  I am now stuck with bill $59 more than what was agreed to!!!
