Bad Service

Vodacom consultant phoned to offer me an upgrade on my contract after my contract ended in June 2023 i refused but she went ahead with the upgrade where i later notice through an invoice that i was upgraded, i then requested for cancellation only to find out i was changed from one package to another instead of cancelling i have been struggling to get this sorted from August 2023 to date still not being assisted, i went to vodacom shop made phone calls but no help just empty promises of getting back to me as soon as they run their own investigations. I am so disappointed with this kind of service. Seem like once you sign the contract with them it should be lifetime not the 24 or 36 months they advertising as the problem started when i was no longer willing to upgrade after 4 years of having a contract with them
