Grouping by frequencies with more than one variable?

Grouping by frequencies with more than one variable?

I am working with this large dataset that looks at a number of different patients receiving services dating back from five years ago. Now each patient is given a unique id number, but there are duplicates in the dataset because an individual could receive multiple different services or come in on different dates for the same service. I want to specifically focus on two distinct services and group individuals based on the number of times they received either service (i.e. Received once, twice,...,6+). Being that I would have to group probably on only id number and service type, I would like any recommendation on how to approach this. I made a small scale example of what my data set looks like. Thank you and I appreciate any help smile
