Uber Eats complaint: You banned my son from working for no good reason

My son worked for Ubereats as a moped delivery driver, about a week ago you banned his account with no explanation. Today you finally got in contact with him and said that he has lost his job because someone sent a video to you, that has been doctored and edited.
My son was released without charge over 6 weeks ago. The police are investigating the other parties.
The police will be in touch with you to find out who sent the video to you, and should you reply to the person who sent it, to let them know, you will be interfering with the police’s investigation.
I think it’s absolutely disgusting that you as a firm are victimising my son, who has got a 17month old son to provide for and rent to pay for his house, as well as bills. How dare you sack him for something that he hasn’t been charged with, and use the excuse that he used inappropriate language to customers is just a total lie.
We are not in the dark ages where you go on a witch hunt, it’s meant to be innocent until proven guilty, and as he hasn’t been charged with anything, he is innocent!!
If you have a claims department, you need to pass this to them, so he can claim for the anxiety and distress that you have caused my son. His mental health is very fragile at the moment and should this push him over the edge, I will be putting the blame with your Company!
