O2 staff refused to give me my receipt back and did not activate my prepaid card per request.

O2 staff in the store refused to give me my receipt back and did not activate my prepaid card per request. I was told to wait for 24 hours but nothing happened. So I activated the sim care on my own. When I check my profile online, I saw an address that I don't know of and the data plan is not what was promised (only 3.5GB instead of 6GB). I am concerned about the how legit the staff was as he did not do any of his job and I have provided my passport information to him. I hope customer service can reach out and solve this for me as well as help me to identify the working staff in that store on 12.Aug.2023 as I would like to file an official complaint.
