Failed assistance

I'm very disappointed with FNB. I went to the bank. They sent home and said that I should phone their toll free number. From my call got cut 3 times, after being transferred to 3 different departments. When I asked them if it's toll free numbers that they gave me, they said yes. So now my airtime is finished and still no assistance. I've explained to them that I want to apply for the Credit Insurance for the Covid-19 lockdown. It just shows that they don't want to help us during this lockdown. I have a link to prove what I need is real: https://businesstech.co.za/news/banking/386841/fnb-says-you-c*****e-credit-insurance-for-coronavirus-lockdown-relief-heres-how-to-check-if-you-qualify/
