Could not escalate dispute to a claim though its been 14 days since payment

I sent a payment to a seller to buy a online Jewellery for $300 on June 23. However after receiving the payment, I asked the seller an approximate ETA for shipment. The seller responded if I ask about this they would stop communicating with me. Eventually the seller stopped responding without shipping. So, I called paypal and an agent created a dispute today (July 8) over the phone with Item not received category. Usually, once dispute is created I will have option to escalate this to a claim. However, I see no such option now to escalate this to claim :(

I followed this link: https://www.paypal.com/us/cshelp/article/how-do-i-escalate-a-paypal-dispute-to-a-claim-help367 , however I don't see the Need Help? button, Nor Review my case button. Is this because my dispute was created by agent over the phone? or did paypal change something?

What option do I have to escalate this as claim, since its been 15 days since I made the payment
