He also does not return to us when called and if we tell him off he jumps at our faces and growls.

These behaviors are displays of dominance. He thinks he is above all of you.
The two things you should work on is;
1- teaching all people are above him
2- bite inhibition & no bite
#1 - Alpha- If you're not already familiar with how someone establishes alpha position in the eyes of a dog you can read some info here;
Letting your dog know you are the boss
and
How To Become ALPHA DOG
I also strongly recommend you read as many books on dog behavior & training as you can. Watching shows like 'It's Me or The Dog' & 'Dog Whisper' can also give you an understanding of body language & some tips. Although I would not mimic Cesar Milans advice on confronting aggression because it can go very wrong undergoing it on your own. Just learn the body language & stick to the simpler, non-confrontational demonstrations of being alpha (as posted on the websites I linked). In addition, if you were to enroll in obedience training you can get help & tips from your instructor.
Your mom will also have to establish herself as being above your dog by also following the alpha suggestions. You, simultaneously, need to show your dog that your mom is above him. When you come home. Ignore your dog & acknowledge your mom for the first 10 minutes. In my house my son is always the first one in and out of the house so that the weakest of us has their position enforced. You can do the same with meals too. Your mom can eat first and anything else you can incorporate into your routine.
This may sound time consuming but some dogs need more conditioning then others. Yours might be one of them & this might be something you need to work on for years depending on your dog.
#2- bite inhibition- Unfortunately your dog didn't learn this as a pup. Bite inhibition is when your dog learns to control the force of his biting. Here's some websites to learn more on that. Ideally, once a pup learns bite inhibition you should then teach it not to bite at all.
This website has some information;
Teaching Bite Inhibition - Whole Dog Journal Article Pay extra attention to the bottom part of teaching an adult dog bite inhibition.
...And as Luna mentioned, your dog can be crated if he can't be trusted. He should also be leashed when he misbehaves. I see it as privilege. And only dogs who behave get more privileges.
