unhappy customer

My husband took a contract for 2 devices, my Samsung A02 core, crashed within 2 weeks, he went to Vodacom shop in waterfall to get it fixed & paid 200 now again within a month it did the same thing, went to Westgate mall yesterday & we were told we have to pay 350. why does Vodacom sell nonsense devices to people? it means in these 24 months we have to pay money to fix this stupid phone. I regret ever advising my husband to take contract phones with this ridiculous company. Their customer service sucks they don't have loan phones I am now stuck with a phone that is not working but month-end the debit order will run if the phone gives the same problem more than once clearly there is a problem with the model itself and they can't even exchange it I am disappointed but I blame myself I know Vodacom is a nonsense company but we still went to take phones this is gonna be a long 24 months with a company that cares about money and not customers we need a law that protects us from such companies. even the consultant never advised that the 20GB was only for that month and going forward we only get airtime and no data it shows that it cares about money and not people what nonsense of a network and company
