Is this normal later down the road or am I just in a unique company?

Background Started working as a POS helpdesk little bit over a year ago making about 14/hr and the job was relatively easy, I did however hate having to take calls all the time and they attempted to push me into customer service which I vehemently refused unless given a raise that is. Since I was hired to be a help desk for our stores not help customers get a refund. Anyway about 12 months pass by and I get an offer for a “promotion” which honestly surprised me since I thought I would be last to get the promotion (I was youngest/newest person on the Help desk). They offered me a Network Specialist position; I did a bit of research and realized this was actually pretty interesting position with possibility to make a lot of money down the road (i.e becoming network admin after all certifications and experience.) I accepted my bosses offer and I moved to my position about a month after accepting (they had to hire a couple of people for replacements).

Tl;dr started pos helpdesk promoted to network specialist

current

I enjoy what I am doing I configure and install switches, firewalls, monitor traffic, and my least favorite installing wiring (which wouldn’t be too bad if they let me dress a little bit more casual for these situations). Anyhow I did not ask while given the offer but I assumed I was getting a pay raise when I was promoted. I did not, then I assumed I was getting a pay raise after being better at the positon I was learning, I did not. I did how ever get a .75$ payraise this month for I don’t know. I was upset but I thought might change once I get my ccna(still working on it).

Currently we do not have a Network administrator, our last one quit after having an argument with one of our IT managers (now our systems admin). I don’t know if this is normal my colleagues who have been working as Network engineers, far longer than I, have told me that the systems administrator has his hands in too many cookie jars, they tell me that they are forced to give him and another IT manager administrative access to our switches/firewalls and apparently the sys admins is the only one that can design/modify our network architecture. Is this a normal sys admin network engineer relationship?

Uh I guess background wasn’t really needed but thought I’d share thanks for reading folks.

was not sure if this goes to /r/itcareerquestions or /r/networking so sorry if this is the wrong subreddit.
