Money transfer problems

I often pay money into my son's Capitec account. He is getting married, and I offered to pay some of his expenses and transferred money into his account. Two days later, I travelled a few hundred km's for work and along the way, trying to buy some food in the afternoon on my way back, my Standard Bank credit card was declined. A *****-flagged SMS appears. After a few phone calls and waiting for ages for someone to answer, explaining in detail my transaction to Capitec, my credit card was active again. After another two days, my son phoned and told me the money I transferred was placed on hold. I again spent time on the phone trying to contact Standard Bank. They eventually answered, after another 15 minutes on the line, they told me it was sorted. The following day, the money is still not active in his account.

I would like to speak to a single-entry person, as was possible not long ago, who can solve this problem. Phoning blind and explaining the problem with every phone call is time-consuming and frustrating.
