Vodacom pathetic service to a long existing client

Good day, I am writing this review on behalf of my husband, Mr. Johannes Kotze Viljoen. On 25 Aug 2020 he completed an online application for an upgrade on his contract linked to his cellphone number, ***. He was quoted an amount to which he agreed. He received an sms regarding the upgrade, but noticed that the quoted amount was almost R150 more that what was quoted. The sms gives you the option to accept, change or reject. He selected change as he didn't understand the reason for the difference in price. No one called him back on his options to "change". He called Vodacom and got sent between "customer services" and "upgrades" and this has been the ongoing situation from Tuesday 25 August 2020. He found out there are additional services that make up this difference and wants to have it cancelled. No one from Vodacom can assist him and he constantly has to be transferred. We even went to the Vodacom store in Upington to try resolve the issue, and they cant because all they see is an open query. It is the most frustrating situation and no one at Vodacom can be of assistance. He does not want to upgrade anymore. He wants to cancel his contract and consider going to another service provider as he feels Vodocom refuses to assist him to resolve the query, cancel the addition services he wished to cancel and assist him with a proper upgrade. The only ref no he has ***. He spent about 2 hours on the phone yesterday in the hope of finding the correct person that can help him, but again no assistance from Vodacom!
