CSL Plasma Questionable customer service at best Grand Prairie Texas

I started donating plasma at the CSL Plasma donation center in Grand Prairie TX, 04/29/13 all was going well, then about May 2013 usually on my second visit for the week, either my pulse was too high or my blood proteins were too high. Eventually I wrote to the company its self and the next thing I know the next time I went in I could not log in and when I went to the front desk, they said I need to talk to someone in the back and the next thing I know they are taking blood and telling me I would hear from them in a week,  a week later after not hearing from them I went in I was told that the machine was broken and when it was repaired they would call me in for the blood test, I was one of six that this has supposedly happened. two weeks later I called in and was told the same thing, if that was the case then send me out for the blood test. I then got in contact with them for an explanation of what the problem may be and could not get a straight answer all I could get out of them is I need to see Doc Robinson I  have not gone back since. They are not hurting me with this behavior they are hurting those who benefit from the medications and treatments that are made from that plasma, my blood type is O but t not sure whether it is positive or negative. I am considering going back to see what happens now so much time has passed.
