Bontias - Incompetence to another level

I had visited my gynecologist in January 2019 for issues I had been experiencing, she then sent me for tests "fasting insulin" and "vitamin d3". After a month, I received a bill from Ampath Laboratories saying that Bonitas had not paid for the tests. I contacted Bonitas who informed me that I would require a motivation letter to pay for these tests. My gynaecologist then wrote the letter which I submitted, a month later, nothing was paid. I called back and was informed they had lost the letter, that was the response! I resent the letter, the fasting insulin was then paid for but not the vitamin d3. I then again contacted them, they informed me I needed another letter! i provided it, they now paid the vitamin d3 and reversed the paymebnt of the fasting insulin! what level of incompetence is this!! do we pay this much money every month for bu@#s#it services? I am being bombarded with attorney letters from Ampath Labs.
