Case number #***0

I've been trying to get back my R1071 back after it was taken from my account, I was told that it doesn't show up on Thier side so they needed proof that it left my account so I sent everything to the document submission page. And now it's been 3 weeks and I'm in so much need for that money and every time I speak with the billing agents they say that they will call me as soon as possible. I'm not happy with the level of service I'm getting at all
