What do you dislike about Zendesk for Customer Service?
We had an extremely frustrating and disruptive experience with Zendesk that ultimately forced us to cancel our subscription after more than a year of unresolved technical and billing issues.
In February 2024, we opened a ticket because emails were not reaching the Zendesk dashboard. We connected Zendesk directly with our IT partners to resolve the issue, yet months passed with delays and long periods of non-responsiveness. The problem was not fixed until October 2024 — eight months later.
Almost immediately afterward, new issues began. In November 2024, Zendesk started flagging legitimate forwarded emails from our own domain as spam. By December 2024, internal and external contacts reported they were not receiving replies sent through Zendesk. We were told Cloudmark updates were the cause and that we simply had to wait for their system to recognize our emails were not spam — an unacceptable answer for a business-critical communication platform. Despite again involving our IT partners, the issue remained unresolved into April 2025, forcing us to explore alternative ticketing systems.
We formally requested immediate cancellation on May 14, 2025, including prorated billing. What followed was weeks of confusion, escalations, and inconsistent communication. After repeated follow-ups, we were told early termination was approved effective July 2025. Even then, we had to correct Zendesk when they nearly canceled an unrelated domain.
The billing process was just as problematic. We repeatedly requested a final invoice and were ultimately told in writing that no open invoice existed for the closed account. Based on that confirmation, we closed our records. Months later, in November 2025, we received a collections notice for an alleged unpaid invoice. Despite documented proof that Zendesk told us no balance was due — and despite the extensive service failures that rendered the platform unusable — Zendesk’s finance department refused to cancel the charge.
This experience reflects serious issues with reliability, communication, and internal coordination. The platform failures disrupted our operations, and the billing mishandling escalated into a collections situation that should never have occurred. For a system meant to support customer communication, the lack of accountability and resolution was deeply disappointing. Review collected by and hosted on G2.com.
