Poor service

I made a payment arrangement with Vodacom to settle an outstanding amount of R1489 with them. This was made on the 7th March 2024 and to date, Vodacom have not sent me communication of a confirmation of this payment arrangement. I've called in numerous times and they have advised that the arrangement will need to be canceled and a new one set up so I can get this over e-mail to *** and 2 agents said it was possible. Today I was advised that it's not possible by another agent and that they will send me an SMS to *** which is still not received. It is getting very frustrating to not have 1 correct story.

All I need is for Vodacom to send me some sort of document over e-mail or SMS which states that amount has been made an arrangement for. Please can this be sent to *** or *** as a matter of urgency.
