Why can’t I get my PayPal credit account re-opened?

Description

Last January I was getting bombarded with calls from PayPal while at work so I answered and said « stop calling me » they put my account as « do not contact » which automatically disabled my PayPal credit account. I always paid on time and most times paid more than the minimum. As of now I even finished paying the balance off. It still shows credit line of 2k+ but no available balance to spend. I’ve called, authorized my account to be contacted, and have done everything I needed to get my account back. Why has it been almost a year and to this date I can’t get my account re-opened?
