1-800-CRICKET has a confusing VR menu and summarily drops your call when they cannot figure out what you are calling about. And the options you are given are likely not what you are calling about.
I probably made some 15 calls before getting to "Zach" to cancel my broadband service.
The good thing about the cancellation, is that you have the option to cancel at the end of the prepaid period, instead of immediately - so, you can use up all the prepaid dollars you have already forked over.
Many of the 15 plus calls ended up with the VRU dropping my call because "they could not figure out what I was calling about and suggested I call back later". On two occasions, I got through to folks in activation, who were going to transfer me to the cancellations department, but dropped my call instead. On the last time, "Zach", also in activations, handled the cancellation.
I guess the lesson to learn is to keep trying.
