I have been racially profiled and my problems are not being attended to

I’ve been having a problem with standard bank for a while! I even had to stop using the bank and bank with FNB! Since the month started I haven’t been receiving my instant money messages.( You know that sms you get when someone sends you money via std bank that comes with the code) I haven’t been receiving that sms even though the sender has entered the correct details. I queried about this problem to std bank via their social media account on Twitter and the first red flag was them answering me 10 hours later😡 what’s the use of having a social media account that’s designed to help customers if you not even going to be active? The second red flag I got was when they told me the problem was with my network provider, upon them telling me that I instantly went to mtn’s(that’s my network provider)social media account and sent them a message telling them in detail about my problem. Mtn rep**** within 5 minutes telling me that Standard/Stanbic bank are the ones responsible for generating the instant money messages, therefore causing me to go back to standard banks private messages and tell them what my network provider said. They then took another 16 hours to get back to me further telling me that I need to register for “my update “ I order to receive the messages which is bull**** to say the least! I don’t need to register anything if I am the recipient of instant money. After telling them that what they are telling me is utter nonsense they went back and said that I need to tell someone who sends me instant money to send me the code which is absurd because the only thing you need from the sender is the pin and the code you get via sms! So I’m total standard bank took 5 days with my problem on top of that they didn’t even fix it but the funny thing is when my white Afrikaner friend sends them a dm with a query they respond within 30 minutes and will even go as far as calling them but because I am black I am getting below par service even though I’ve been a customer for a very long time
