PATHETIC SERVICE FNB BANKING

My cellphone was ****** this afternoon out of my bedroom. I wanted to block my FNB simcard but all I heard since 14.50, is there are a huge amount of people waiting ang and I must stay on the line until a consultant take my call. it is now 17hours and none whatsoever response from FNB. Vodacom blocked my number I used so I can't try to go online in the app. how pathetic can a bank's service be? there is actually NO service!!
