It sounds like you are working for a relatively small company? If so, a little education is in order...
In general, when a company hires you, they are hiring _you_, not for the skills of the day, but for your potential in the future and your ability to extend into new roles. As an employee of a small firm, you are expected to wear different hats, grow with the job, be flexible, and fill in holes where they need to be filled.
You sadly view yourself, instead, as a commodity, a replaceable set of skills; a robot. Your company was hoping that they had hired an all-around joe who was able to handle multiple new responsibilities as they came up. Instead of firing you, they let go some other poor slobs, which should bolster your confidence that they like you and want to trust in your talents.
No employer is perfect when opening a new position, and the business landscape always changes. You should never expect to be doing the exact same tasks in which you were hired for. And if you do, you probably need to work for a large business or the government which can help you in your endeavor to be plugged in mindlessly to the cog.
Your employer has obviously made some tough decisions and now needs you to perform some other duties. How exactly does that necessitate a pay raise, or a new title? Just do the work that is asked of you. You do their work, you collect a paycheck. It's really that simple. Titles are stupid and meaningless. Your new set of responsibilities does not imply a pay raise.
So, work hard for your pay. Become irreplaceable. Grow in your talents. Demonstrate your continued loyalty and support of your company and its managers. And if the company is any good and values your contributions, you will be rewarded appropriately.
And if you can't do this, you can't get over taking on new responsibilities while not getting a new title or some additional pay, then good luck selling your set of wares to the next poor schlub that might decide to hire you.
From my experience, the best jobs are the ones _without_ titles. What exactly again does a title give you? Prove your worth, and a pay raise (and more) may very well come your way.
