Wesbank does not know what service is!

My mistake, am bedridden with a crocked foot, was doing some banking and visitors arrived; so in the tumult, sent money to my Wesbank account instead of to my credit card. This is Wednesday the 24th Feb. No problem, spoke to the call centre and was told to email proof of payment, although they can see the amount paid to my account which reflected immediately; (Wesbank, a division of FNB, work it out); it will take 24 hours to refund me my money??? No worries, month end is coming, but 24 hours, right? Sent the email and proof within the hour. Zero response. Nothing. Yesterday called again. After all the self service monologue stuff, spoke to Mariska, she says no email received at all, please re-send and she will put a note on the system. Apparently, and this is the 21st Century; their system is so backed up that the emails are taking over 2 DAYS to get through!!! So sent it all again yesterday. Still a ZERO response. I cannot go there due to my injury, but they don't want to see me either! They want me to self-service myself with their system, which takes over TWO DAYS to receive emails from the clients paying their interest and salaries. Interest? What about my interest? Useless.
