Appalling service from Absa

On the 12th of December 2019 I went to Standard bank atm to withdraw money but I never got my money but the SMS notification showed that my money was withdrawn, so the following day I went to my branch which is Absa bank I lodged a complaint and then received an sms saying my complaint is being investigated and I will be contacted on the 30th of December 2019 but till today I still await a call from Absa. I eventually decided to call the guy who said was investigating my claim Tshegofatso Mkhine who repeatedly said they still investigating. I'm applaud by the level of service that Absa is providing to their clients, they fail to deliver on their promises and take people for a ride , I personally feel failed by my own service provider and no longer wish to make use of their services.
