RCS / Jet account payment not allocated on my account

Jet account payment:

Please kindly update my Jet account on your system and allocate my payment for October, I paid this on the 30 October already and it is getting frustrated that I keep getting letters and phone calls stating that my account is in arrears.

I paid via easypay using the easypay reference number on my statement: ***

I paid the R219,78 that was due so please allocate payment and update my account on your system.

Please don't mess with my credit score/profile as I always pay the account on time and my account is up to date, you send me a statement for November stating that the R219,78 is in arrears which I paid already!!

I did send the proof of payment to this email which I got via telephone from the Jet enquiry department - ***

Please kindly sort this out ASAP.
