Telkom not providing devices 2 weeks after upgrade

I firstly requested an upgrade of my 2 mobile numbers via the online portal, however I never got feedback around this so after 3 weeks of waiting I went to the store to proceed with an upgrade, which was completed however i never got my devices and after trying many avenues, even going to the store on several occasions i still have not received my devices, which are P30 Pro and P40 Pro. i am going seek legal advice around this matter to see if Telkom is in breach of contract, i have already received my upgraded bills which includes the devices which i never received.
