Very annoyed and frustrated for the bad ongoing service and treatment

I have a type 1 diabetes daughter whom when the pharmacy claimed under her chronic script, claim went through but as for the Libre sensor which nomarlly covers from the risk benefit, they paid it out of the medical savings. I sent all call references and it been 2 weeks and no one has resolved the matter as promised. It's not the first, nor second but it's been ongoing whenever I ask them to solve their mistakes and wrong doings, I have to end up here for clarity and resolution
