I have been trying for 4 days to renew my Onoff number, but the payment system keeps failing. I tried different bank cards, browsers, clearing cookies, and both the app and website. Nothing works. I contacted customer support several times through tickets, forms, and emails, but received no response at all. Now my account is suspended because of a technical issue on their side. I urgently need this number for professional purposes, as recruiters use it to contact me. Very disappointing customer service and no support when it matters most.
