Constant Contact Misled and unable to get resolution Internet

I am so surprised by the disservice that has been provided by Constant Contact.  I was misled by an account rep regarding price.  I was given a price of $65 and that a 5% discount plus a 25% discount would be applied.  Only the 5% was applied to the initial charge.  I never received a response about price adjustment when I learned that my campaign would include just over 10,000 contacts instead of just under.  I learned when I got the bill that the price jumped from $65 to $185. 

Had I received a response and learned of the price in advance, I could have made adjustments.  Not receiving a response, I just worked under the assumption that the price could be as high as double...very surprised to find it was triple!  Regardless of the total contacts, my account rep informed me that there would be a 25% discount that was never applied.  But I am willing to accept that consequence.  Not told of recurring charges.  The service represented was not delivered, including that my first "campaign" email was going to be developed for me by their marketing team within 48 hours.  They were unresponsive and finally responded after the campaign was complete, more than a week later. 

I am so frustrated because I have been trying to reach my account rep, but no response.  I have tried to reach the customer support, but hours are so limited.  The only thing you can do online is upgrade your account.  You can not cancel or downgrade or send a request for assistance. I have been overcharged and have been trying to get that corrected.  I also have requested cancellation in writing to the account rep since mid-November since the service with my first use was much less than promised.  But the cancellation has not occurred.

What needs to happen ( 4th request):

• Initial charge in October needs to be adjusted to accommodate for higher than expected contacts from over 5000 to just over 10,000.  But then 25% discount was supposed to be applied and never was.  Also, be aware that $61.75 was already paid for October.
• Charge at end of November and end of December, each at over $185.25 needs to be reversed

Total charge should have been $138.94 (185.25 - 25% discount) for the campaign (email campaign created and sent Nov 2, 3, and 6th)

Total charges billed and paid: $432.25

Refund amount due: $293.31

If this can finally be addressed, then I can submit an update to this report.
