Wearable e-sim

I have been a loyal customer to MTN for the longest time but now my loyalty is tested. I have been sending emails and calling call centre to try to get help with esim activation for my watch instead I get pushed from pillar to post. This has been going on for months now. I am so disappointed in MTN . I doubt I will renew my contract with MTN. I have been to different stores to try and get help but they are also not helping me
