SIM still not active after 1 month, no communication or assistance

Worst service ever. Tried to buy a data contract in store for Black Friday on E-Sim (21/11/2022). I was advised I have to wait a day for the sim card to be activated and I would receive the QR code via email. When I received the QR code, said it can't be activated, need to contact the service provider. After various in-store visits (was advised to go to an alternative store as well) and multiple e-mails this still hasn't been resolved. I receive absolutely no response via e-mail for the last two weeks, when I visit in store I am told to wait for them to contact me till the consultant will be back at work. It is now the 23/12, and still this hasn't been resolved. I however have been billed for the service, and had to pay activation fee. The call centre is absolutely useless, it takes 20min to get the call answered, and they have not been of any help or been able to redirect to the correct department
