BioLife Plasma Services review: Customer service

Went to call this location today, only wanted to ask a simple question on whether or not it would be ok to donate at this location even if I went to another location about a year ago. In the midst of talking I wasn't warned I would be put on hold and got put on hold for a brief second and then they hung up abruptly on me. Immediately called back and was told I would be put on hold. Waited for 15 minutes and no response. At this point I was already close to the location and walked in to ask them since they couldn't talk to me on the phone for some unknown reason. Went in and was kind of greeted like I wasn't really welcome and they had a bit of a snippy attitude with me and even to one of the donors inside because they weren't sitting at the right spot near the enterance? The way the lady talked to me also not only confused me but she had a bit of a weird attitude like she was talking to me in a street lingo? I do not know how to describe it but it wasn't clear nor was it really informative or professional for this line of business. I don't intend on going to this location and felt so disrespected like my time was not even valued or welcomed. I really think this store should be taught better on how to respect their customers who come in let alone even talk to on the phone. What had me also upset was when I came in no one was on the phone with anyone so it honestly told me that they didn't feel like answering my phone call. Will not be returning here.
