My experience with this app's customer service was, without a doubt, the worst I've ever had. It all started when I simply asked for assistance with my account. During my free trial, I noticed I was being charged for international calling, even though I was supposed to be on the free trial. I knew this wasn't right, and I wanted to understand their pricing structure once the trial ended. To my shock, the customer service representative's response was to yell at me and dismiss my concerns. I even raised my voice in frustration after his unhelpful attitude. It's worth noting that this whole ordeal began because I wanted clarity on charges while on a free trial. The representative's statement that I "couldn't get cancer because it was free" was not only unprofessional but completely irrelevant to my inquiry. Despite explaining my concerns multiple times, he continued to yell and belittle me for worrying about charges during the free version. While I acknowledge that this app's software is neat, I cannot stress enough how horrendous their customer service was during this interaction. I would genuinely hesitate to entrust my business operations to them, especially if my call center or operations rely on their services. It's truly disappointing because their software is decent, but their customer service is the worst I've ever encountered. My advice would be to steer clear.
