Very bad service received

I'm not happy at all with a service I recently received at capitec I have been banking with them for years but they disappointed me and I'm thinking of moving all my staff to the other bank and close this account completely. There were transactions happening on my account and left my account on a minus, i ended up canceling my card because I was suspecting ***** when I went to the branch they told me about the system problem and when I ask for a new card they told me that they will charge me R70 of which is unfair because it wasn't my fault. The person who assisted me was very rude as well so I'm tired of capitec bank🚮 they decided to deduct money from my linked account to pay that minus on my account without even contacting me.
