Hello again stipe177,
Thank you for providing additional information. I understand that you have already tried all the suggested steps and that both Apple and your phone provider have been unable to provide a resolution, with each party blaming the other.
In situations like these where you have exhausted the troubleshooting options and both parties are not able to provide a satisfactory solution, it can be challenging to find a resolution. At this point, I recommend considering the following options:
1. Seek alternative payment methods: While it may not directly resolve the issue with adding your mobile phone number as a payment method, you can explore alternative payment methods for your App Store purchases. This could include using different credit or debit cards, prepaid App Store gift cards, or other available payment options.
2. Consider reaching out to Apple or phone provider through different channels: If you have been contacting Apple and your phone provider through phone support, you may also try reaching out to them through other communication channels. This could include submitting a support ticket through their official websites or reaching out to their social media accounts. Explaining your situation again and providing any relevant details may help in getting a different perspective or additional assistance.
I understand that this situation has been frustrating for you, and I apologize for any inconvenience caused. Unfortunately, if both Apple and your phone provider are not able to provide a resolution, it may require further investigation or changes to their systems to address the issue.
If you have any further questions or need additional assistance, please let me know. I'm here to help in any way I can.
Best regards,
Lugab
