Shocking customer service- beware!!

Made an electronic payment on 02 Feb, received sms from Wesbank a couple of days later saying I have not paid my premium. Unfortunately I get not request a proof of payment when I did the transfer. I have literally been mailing their customer service since 09 Feb, multiple emails sent per day and all have gotten is automated responses and 2 requests to send through proof of payment. Unfortunately I cant get to the bank and in daily mails sent I have given them the bank account I deposited into and the reference number, my account detail etc. Not one person has been able to confirm if they received my payment or why they cannot find the payment- the amount is over R10 000 and not 1 person can tell me where the money is? Surely if payment was made on 02 Feb it would clear the next day or 2 and one would think that having details on which account I deposited the money into along with reference number and ALL my details that someone in their finance department can check those 2 days of monies received and they will quickly pick up my payment?? Be careful of this company- its clearly lacks internal infrastructure, their customer service is a nightmare and completely useless and they just dont respond to client queries and are definitely clueless. I would advise deal with another company rather than Wesbank- it will save you alot of unnecessary struggle and stress when dealing with the company!!
