@natalia2019 hi and a big warm welcome to Giffgaff the network and the community. Take a little time to explore and become familiar with your dashboard in your account, it really is the heart of your giffgaff. Can take a little getting used to but once you do it all falls into place.
Any help you need, no matter how silly you may feel it to be, skip along to the excellent help forum as there is always someone online to assist, the members have a huge knowledge base and are a very friendly bunch. I'd advise if you are faced with any issues at all to first ask before attempting to work through them on your own.
