You can't fix that. Send the pic to the seller and demand satisfaction. Probably the bike was not packed properly for shipping, or the shipper brutalized it.
If you can't get it replaced for free, the part is $20: https://www.amazon.com/Shimano-Tourney-Derailleur-RD-TY300-Direct/dp/B01D2WQ0TM and you can install it easily yourself.
You may or may not need to take the bike to a shop to have the derailleur hanger (silver piece) straightened. If you bought the bike mail-order, ask them to send you a new one of those too.
Upgrading it will be quite expensive. However, it'll provide you with a wealth of knowledge, frustration and, at the same time, fun.
Depending on your existing hub, you may or may not need a new hub to put your new cassette on.
With a wide enough range of gears on your rear cassette you can get away with a single chainring, so there will be no need for a new crankset/front derailleur/front shift lever.
As /u/fclbr said, you can choose downtube shifters in order to keep your existing brake levers. There are also bar-end shifters, and if you go for a single chainring, it won't be that expensive.
All-in-all, consider if this bike's right for you, size and geometry-wise, as your decision may be a bit rash. If it is, then I'd say go for it.
Rear derailleur - $20
Cassette - $20 - I recommend going for the 34t max sprocket. It'll allow you to stick with a single chainring
Bar-end shifters - $55 - they are 9-sp indexed, but they also work in friction mode, which allows you to freely adjust your gear
Downtube shifters - $14
Cables/outer cables are negligible costs.
