No response

I made an eft payment on the 24th of April 2020. On the 4th of May I noticed that I made a mistake with one digit when I entered my account number as reference. I sent the accounts dept and customer service dept an email with proof of payment asking them to please fix the problem for me. No response for several days from Edcon, so I phoned again on the 14th of May and a very polite person with the name Tumelo assisted me and told me, I must sent proof of payment with an email explaining my situation to *** and that I must check my account on the 26th of May, because by then the problem should be rectified. I have checked my account today and still no payment shows on my account. I've been trying to contact customer service with no luck. I am very dissapointed! After all my phone calls and emails, I still have heard nothing from Edcon.
