Poor customer service
The customer service relating to issues is very poor. I had two cancellations to a repeating appointment. According to support amounts are refunded within 7 to 14 days. This did not seem to be the case. The one was canceled after numerous emails but the other is still in dispute.

Customer support takes 2 to 5 days to respond to a single query (618353) without useful solutions. The response is so slow that I was asked for an update since my last email (twice).

In short, the service works, but the customer service isn't great.

Details about the dispute:
I was charged for the appointment for the 25th of December 2019 on the 27th of December 2019. Supporting evidence was provided by means of redacted bank statements, screenshots of my online banking and a reconciliation of all payments made to SweepSouth. 

The funds have not been cleared on my side, but it's not something I can access. SweepSouth gave feedback that the transaction will be canceled within 14 days. Its been way past the 14 days and the funds is still not cleared/canceled. This is a problem with the service provider SweepSouth uses for their payments, but SweepSouth refuses to recognize the problem.

This wouldn't have been a problem if decent feedback was received from SweepSouth or if you knew they were working on fixing it. In this case, nothing happens.
