Worst service -

I have been with one plan for over 4 years now or nearly 4 years. After being with them for so many years and getting the same script over and over they tell me now that the script I got now recently does not apply to the medication I can take. When trying to as the lady to justify why not as they approved all the rest she keeps telling me that it's because of the amount of previous months. It's the 1st time that i hear something that and i still do not understand how u approve everything all the rest but reject this one. I am so crossed with the lady that assisted she told me no I cant transfer you to management. Is this the service that I am paying for? Is this what you call customer service. You approve a payment for a script that had meds on that is not even a prescription. I have never felt so irritated before honestly very bad service that and the fact that you scratch into my health so unprofessional.
