BioLife Plasma Services review: policies and procedures

I have been a very good, consistent donor over the years for BioLife and you are always trying to get new donors that come and go. What about the donors that are loyal about donating twice a week?
I called with some concerns and hoping for a change with voicing those concerns on Nov 11. I never got a call back, so I called back on Nov 19 again with a request to have a call back. Your marketing dept chose to email the local center to have them call me. The reason that I wanted to talk to your dept was because you make the policies and can make changes to them. Not the local center. I would think that you would welcome suggestions from your long time customers.
I was told by the local center that they didn't have a phone number for their main office since Takeda took over. I did find it and gave them a copy. However, yesterday when I spoke to your receptionist she asked how I got the number. Now, because of no response from you I'm wondering if I was asked because you don't welcome customers calling.
I am not happy about not receiving the customer service that I think I should. Who can't spare 5 or so minutes to call a customer? Seriously, how you handle this complaint will determine if I continue to donate.
