You need to be more assertive in how you request your salary review. If your manager agrees to a Monday or "tomorrow" you need to follow up with a specific time. Force your manager to commit to a specific time on a specific date. Once this has been done, you send an official meeting invitation for that time/date. If you are both working in person, I would walk into their office at the time of the meeting and let them know you are there for the salary review.
If your manager is still unable or unwilling to meet with you for your salary review, I would escalate thisreach out to HR but don't immediately throw your manager under the bus. Kindly and innocently ask HR "when is my yearly salary review? What is the process for setting this up?" and see what they say.
If you continue to struggle with this then it may be time to start looking for a new company to work for. I have worked with managers like this that appear to be too busy or to pre-occupied with other things to effectively manage and I know how frustrating it can be. If you want to commit to working for someone like this, you need to be more forceful with your requests otherwise your best bet is to look for somewhere else to work where hopefully your manager can actually perform their duties.
