Pay service fees to a bank that has non existent customer service

I am utterly disappointed in the service that I have been receiving from FNB. I have recently joined this bank but I am honestly regretting this. I noticed that there are ridiculous service fees that are being deducted from my account, I pay R105 pm, now there is a surplus of R75 over and above my monthly service fee. This is bull**** honestly! I had called FNB on numerous occasions to try and change my monthly service fee debit date to the 26th of each month but this has not been done, it's now 3 consecutive months. I had also purchased a few lotto/ power ball tickets within the respective timeframe, I was told that my purchases had expired, yet FNB deducted funds from my account. I had sent many emails for someone to contact me but this was never done. I feel like this bank is just out to ******* customers, let's not even talk about how customers get ignored when trying to rectify banks errors. Wake the f*** up
