Poor pathetic customer service

In April I emailed Standard Bank requesting a 3 month payment holiday as I was nor sure about what payments my company was going to arrange for the staff due to lockdown. I receives and email from the bank stating that I have been approved the 3 month payment holiday and that all my financial obligations would be stopped for three months, I was so happy as this was a major weight lifted off my shoulders...to my surprise the bank tries to take debit orders off my account at the beginning of May and there was no funds available, so now this means that for al the debit orders that came back as unsuccessful, I am going to be penalised by them charging me for unpaid debit orders. I contact the bank and they give me and email address to send my complaint to which I did mid May and to my surprise on Thursday 28 May the politely debit money again for my loan and for interest charges on my overdraft which obviously now put me in such a predicament as I am currently the only one employed and only receiving money from the unemployment fund which our company app**** for on my behalf, I called the bank on Thursday evening and explained mthe whole story to the agent, requested that monies taken be refunded and a manager to call me as not one of the agents I deal with can resolve my issue and to date no one has to call me to resolve my complaint...this is pathetic that your bank says they will assist u in this challenging time of this pandemic which we are faced with but then they do not stick to there end of the bargain and u sit with a headache of financial stress..deeply disappointed and truly disgusted at the way they conduct business..i want all monies taken feom my accoynt refunded and if this does not happen i will rake legal steps..I will be cancelling all my bank accounts with Std bank and go to a bank who has more understanding towards there customers needs..I will also take this complaint further, eg the ombudsman but this type of cusromer service from them is just not acceptable at all...from a very angry customer..
