CAN'T BOOK MY LAPTOP IN FOR REPAIRS

I bought a laptop at cell C in October 2022. I was promised that the laptop comes with a laptop bag, I did not receive it, I called them, each time they transfer me to the relevant department, the line gets disconnected. I sent them an email and they never responded until I gave up. The laptop now can't connect to the internet. I have been calling them, opening different cases and closing them before they were resolved.

I was put through to the technical team so they can book the laptop for repairs, the technical team said that they can't book the laptop without the IMEI which is found on the copy of the contract. The copy of the contract does not show such a number, it is blank where it should be displaying it. Now I'm stuck I don't know how I can get my laptop to connect to the internet since this is the service provider's s issue.
