Paypal not assisting in getting my OTP for over a month

I have been struggling to log into my PayPal account for a month as I am not receiving the OTP via sms. I was told it is my service provider, I contacted them and they said it's Payapl. I am being pushed from pillar to post and no one is assisting me. I want to change to receive the OTP to my email and not to my cell phone number but no one is helping me.

It's been a month now and I still haven't received any assistance in getting this sorted. Either change the OTP to he sent to my email or remove it as I urgently need to log into my account.
