Thank you for reaching out to us. I'm sorry to hear you feel as though our services haven't met your expectations for the price. Perhaps I can provide some insight.
Would you be able to clarify as to what "services are less?" Are you referring to a feature that you might have had access to in the past? Or is there a specific capability that your subscribed service level should have access to?
If your price has recently increased, it's very likely that your contact numbers have recently increased over a previous threshold. Managing contacts is a good way to ensure that your email campaigns are reaching people who engage with you. There are a number of ways to manage your contacts, therefore I'd recommend taking a look at some of the following articles to learn some best practices with contact management to ensure higher delivery, open, and engagement rates.
However, if you truly wish to cancel your account, then please reach out to our billing team so they can finalize the cancellation and make sure all billing credentials are purged from the account. On Saturdays they can be reached through our Support line, and during the week they can be reached through their standard phone line.
