Absa vehicle finance nuisance

What an absolute pathetic ban****!! Made a payment into my vehicle finance account on Friday the 28th of September due date every last day of the month. Got a phone call on Monday the 1st to notify me my account is arrears. The lasy then looked into the statement and said i must not worry the payment is reflecting. Surely if the end of the month falls on a weekend should they not wait a day or two for the payment to reflect? She then confirmes that she will put a note on the system so that i will not get another call for the same issue. They have been contacting me every single day after that with the very same thing! I then forwarded the proof of payment to Gerhard today 3.10.2018 after he told me that i have maybe paid it into the wrong account, yes the same account i have been using for the past 5 years!!! This wasn't the first time this has happend!! Pathetic ABSA!! I will NEVER recommend you to anyone!!
