Worst service ever

I don't understand why they just don't pay the bills they should. My son and I are both kidney failure payments. I have send a bill for his kidney specialist who looks after his chronic condition, guess what not one payment made to her, the funds are there but not one payment, does my emails or her emails get responded to no why should hey, I mean there is no reason to respond to a concerned client, 26 October 2015 I got an email that said you will have a response in 48 hours. I must be stupid or something but the 48 hours passed when again? this wasn't even the first email, wow you guys are just amazing at service delivery. I continuously land in hospital because you would not pay my antibiotics, nor my sons medications so we will be in hospital on your cost, since you seem to have money to waist rather pay the medications, which are for chronic conditions. I am so tired off taking to you guys, are you just deliver poor service.
