Cellc bad service

Good day

I'm very upset and disappointed.. I made a mistake with my reference number when paying my cellc account on the 3 January 2023.I phoned cellc and they let me know that I have put in a incorrect reference number the lady on the phone advice me to send it thru the proof of payment which I did... I went to the store they emailed the proof of payment multiple times... I phoned again when I realised my phone was cut off.. I was advice to send the email again with the proof of payment which I did.... Collections department phoned me also to find out why I haven't paid I told them also the story they advice me to send the proof of payment I did that also nothing.... A lady from cellc *** advice me to also email her the proof of payment which I did but still nothing... I Mean I know I made a mistake with the reference number but still why is it so difficult to just link the payment to my account... Now my phones are cut off and I'm dealing now with this.

I just want it fix!!!!!!
