Nedbank Are *******

I am literally bemused with the service from Nedbank and utterly upset at this point.I intially took a loan from Nedbank and a few months later I was retrenched.I claimed from the retrenchment cover which was fine however as soon as i joined a new company,I requested via email several times to reinstate the debit order which was never done (according to the pathethic call centre agent I had to phone in to do so),really,Its the digital age and your agents dont consider email to be a form of communication?Anyway I get a call from an agent a few weeks later to say that Im in arrears and I have to pay the intrerest charges and so forth.I asked you to reinstate the debit order which you did not action and Im in arrears?So ive had to make arrangements for the additional costs and pay i additional charges for your *********** staff but wait it does not end there....2 months ago,my account has been debited twice and this month September 2019,the account was debited on the 20th instead of the 25th as per usual.Is this an acceptable form of client abuse Nedbank?I insist on rectifying these issues,I can provide full proof of my issues and where YOU NEDBANK and your staff are costing me inconvenience and additional expenditure for your incompetence.
