Based on your labs over a year ago, your Free T4 is on the hypO side of normal. Sometimes when one is either too hypO or hypER, the Calcium levels as well as other levels such as Glucose, Potassium, etc. can be high or low.
I suggest labs being done more often (I go every two months) of the Free T3, Free T4, and TSH at least. You want to get the Free Ts at mid ranges, at least, as to not to have problems with any mineral imbalances in your body.

P.S. Yes, I know what you mean. I never get a 'live' person to get in touch with me with any concerns that I may have with my health. Same thing if I use emails to get in touch with the doctor or the staff and they don't get back with me. Many things I've had to figure out on my own and with the health forums on the Internet to get the help needed.
