Bank charges each time money is deposited into account!

I have a FNB cheque account which should charge me R105 a month, but my charges range from R209 - R339. when you call in and they eventually answer you get an explanation that does not make any sense. When onE pays for something with the card (R100 and over), you get an sms notifying you that money is being deducted from your account, allocation to the merchant. money shows under pending if the merchant delays to bank. now i have this new story from FNB that they don't actually deduct, they just put it under pending, and that the sms you get is not a guarantee that they have deducted the money from your account. i have three charges stating that I have made a transaction when there was "no money in the account" and FNB honored that payment. you cannot even get R25 airtime from FNB if you balance is R23 in my account. i have two charges of R55 and one for R82.50 that i have picked up so far on my statement. The dates on the statement are all wrong, now how can they tell me that they carry forward correct balances into the new new month when they allocate own days onto the statement. I have spoken to Fortunate, Thabo - team leader, Candice and to Verlice Goliath. Verlice Goliath told me that she has sent my query to another department, she has requested a reversal for the charges because she and her team leader saw this error, this was on the 9th of January 2018. Verlice assured me that the process will take 3 days. I called in on the 16th and Fortunate told me that Verlice was off. Verlice was unavailable on the 17/18 and 19th, apparently she is the only one who can assist me since she was the one who has logged the complaint. The team leader Thabo told me that FNB paid on my behalf (really? did with a loan application, you just helped me!1?), when I clearly told him about the incorrect dates and that before i made the purchase i have taken money out of my savings and deposited into my cheque which had a positive balance. on the 15th there was a debit order reversal of R124.50 by FNB, I DID NOT request a reversal on it on the 15th. when i called in to find out about the reversal, i was told that they don't know how it was reversed but it is showing a time after 8:00 am that it was reversed on the 16th. i Told Candice Brown that i did not request for FNB to reverse that debit order, I want to know how it was reversed. she did not give an answer. This is clear to me that there is someone messing with my money at FNB because every single time there is a deposit into my account charges come from all directions. WHAT KIND OF A BANK IS THIS AND I FEEL SORRY FOR PEOPLE WHO DON'T CHECK THEIR STATEMENTS-- PEOPLE WHO BANK WITH YOU!!! you try to justify your errors instead of correcting them.
