FNB poor service

I'm so disappointed with this bank. I have a private wealth Cheque account. I'm doing business where I have to bank money with a lot of coins every day. Every time I come, there is only 1 teller to help all the people where 1 person take more than 40 minutes at a time. After waiting for my turn for 2 hours they tell me the safe is full come tomorrow. I have to take my coins to Capitec bank in order to transfer the money to fnb. Atm weekend is off line putting us at risk of sitting with money the whole weekend. Their service is very slow, I have to stop my work to stay in a bank the whole day only to be told i have too much coins. Now I have to buy with cash without depositing.
