Poor service in accounts

I have been with flexicare over a year now. And i am absolutely shocked with how negligent the accounts department is. In the past 13 months every single month i am held liable for costs flexicare did not cover costs paid out of my own pocket. Everytime it takes them 2 to 3 months to fix the ussue in that time 3 more issues have rised up. Emails are being ignored. At this point in time I'm actually working for flexicare it takes me time reconcile their account and point out their errors. This is absolutely ridiculous. 💯
