No refunds

I am having the worst experience with Rain. In March I paid my full installment and no internet access. After several phone calls, emails and messages, which cost me money, time and frustration, it was determined that there must be something wrong with my device. I was informed that I must keep my line open because a technician will call me to test the device. A week later, still no phone call, no internet and more phone calls, we eventually canceled our Rain. We were assured that once the device is collected we will receive a full refund. The device was eventually collected 22 April. Today is 6 May and still no refund. We have made countless calls. All they can do is escalate the matter after which we get an email te say help is on the way. We have been told billing department will call us, the refund takes 7 to 10 working days, but to date no phone call, no refund and no assistance. But when it gets to you having to pay them there are absolutely no delays. I doubt I will ever see that money. This is not only ridiculous but also pathetic. I won't advise anyone to use Rain
