Customer Service and Reimbur*****t is the worst!!

I am extremely disappointed with the lack of communication from Supersonic. I need to keep following up with them regarding a payment that is due to me as they deducted money from my account in February after I had canceled in December. I am still waiting for the funds due to me, no estimated times communicated. I also went to their offices to drop a router off and no acknowledgment regarding this either. I would never use this service provider, neither would I recommend it.
