Poor telephone customer service from standard bank collections

Just need to note that Standard bank must teach some of their staff telephony customer service. Was on a call with Mpho from your collections , he was being sarcastic with his responses and waited for me to ask him what he needs to identify me and assist me. He also could not give me some assurance like an email or a call ref to the least that my request was done to change the debit order date as my original contract agreement still has the original one that i have asked to be changed. All he said is that if things dont go as expected and the debit runs on the date i dont want , I can just call and say i spoke to Mpho.Honestly this is not expected and is rather very poor customer service. I am so disappointed. I understand that people tend to have bad days but tdont rub it out on customers as he has now spoilt mine as well .
