Trustpilot
Reviewer Notes
Reviews describe dreadful customer service, unresponsive complaint handling, equipment leasing practices where merchants were not told they could buy equipment (leading to expensive multi-year leases), and continued charges after cancellation.
G2
Reviewer Notes
Mixed; enterprise reviewers acknowledge Fiserv's global reach and scale; complaints focus on high pricing and customer service quality.
