Credit Card Division - no service at all!

Standard Bank Credit Card *** Name: LB Roodbol. MANY phone calls refers. I have accidentally transferred R30,000 into the mentioned credit card [which I cancelled/stopped/unused due to various ********** transactions!]. I decided to make use of my visa card instead. I asked Standard Bank Card Division to REVERSE the transfer from my cheque account into this [cancelled] credit card, which has not been done! Being a client of Standard Bank for 40+ years, I really find this unacceptable!! They promised many times the reverse will be done within 24 hours, which has not taken place.
