I was trying to update my phone number as I just got a new number. However, when I update it in Paypal settings, it tells me that my phone number is not a valid number. I have been using it for a while for calling and texting and I don't think there is any problem with my number. I tried to call the customer support, but apparently it's impossible to get connected to a real person before my phone get hung up involuntarily. I am wondering how I can have this issue fixed?
