Exploiting the elderly and unauthorised upgrades

I’m utterly disgusted by this network provider’s services. I don’t know what’s worse, hiring *********** staff who don’t know how to do their job or letting employees manipulate the elderly into taking unwanted products. For months my mom has been paying for data services she has been trying to cancel since feb 2024. She got a call around January were an agent tried selling a new product to her to which she blatantly refused explaining that she is retired now however agent decided to go against my mom’s wishes and upgraded her package, fine she let it be. Now bills are ranging from R150 to +-R700 randomly on a monthly basis with no explanation given to her. Everytime Vodacom fails to debit from her account on the agreed date, even though there is money available, they charge her penalty fees for their own negligence. The store employees are just useless they couldn’t even explain their own account statement to us. There is absolutely nothing more we want from Vodacom except to cancel this stupid contract. Account is I***.
