Failure to remove a 10 gig bundle and correct the invoicing

I have been struggling since May 2023 to remove a value added service on my account. My account was paid up to date on 18 May 2023. I thereafter contacted Vodacom and requested that the 10 gig per month recurring data bundle be removed, as my account was then up to date and they would then be able to remove the bundle. However, Vodacom did not remove the bundle and on 1 June 2023 I was again invoiced for the 10 gig bundle. I again made contact with Vodacom and asked why I was invoiced for the bundle that I had requested them to remove. I was that it could not be removed until the invoice was settled. I told Vodacom that I could not settle the invoice until the 10 gig bundle was removed. The matter was escalated, but never resolved. I have been continuously invoiced till present and have continued to contact Vodacom to resolve the issue. Vodacom still does not understand that I cannot and will not make payment to the account until the request to remove the 10 gig bundle is resolved and invoicing corrected accordingly. The account is in arrears due to the incorrect invoicing for a bundle that was supposed to be removed.

I have been a long and loyal Vodacom customer and wish to continue being a Vodacom customer, however this lack of understanding of the situation from Vodacom cannot continue.

Please, there has to be a way to reverse the invoicing to not include the 10 gig bundle from the date that I had settled the account, provide me with a new invoice and then I shall pay my account accordingly.
