Unhappy customer service

Good day, my account was in arrears so I made payments yesterday, but for some reason Vodacom didn't allocate the payments to my account as yet, normally when I pay through the app, it is immediately done, now I am told that it can take up to 48 hours, really????? What are your accounts department doing??? Also why is nobody answering your customer service line??? It is as if Vodacom is not working anymore, like they are just there to take your money and then leave with it, no respect for their clients, and this is not the first time I complained, I demand that someone will phone me to sort this out, if not, I am happy to take legal action against vodacom, why must something bad to happen before Vodacom can fix it
