Worst service ever!

I've never experienced such terrible service before. I've been trying to reach the company for the past 10 days and I'm not going through. They debited my account but I still don't have my device and it's more than 20 days now. I want to cancel their services and get a refund since no device was delivered as per the agreement and I still can't get through to them. I think I've called in 20 times now and no one is picking up. I'm not sure if this is a **** or not but the service is so terrible!!!!!!
