Hi Jonssonjunior94,
Thank you for posting and welcome to the Community Forum!
I’m very sorry to hear this.
This sounds like potentially a web browser related issue. Have you tried changing the web browser or the device yet?
You will need to add a new phone number, set it up as a primary and only then you will be able to remove the old number.
Regrettably we can’t see your account details here. If you need any further assistance, I would recommend you calling PayPal Customer Services by clicking onto Contact us on any PayPal page as they will be able to review your account and provide you with the best course of action.
We also provide support via Social Media (24/7). You can contact us directly on Twitter @AskPayPal or on Facebook at https://www.facebook.com/PayPalUK.
Hope it helps.
Anna
