Vodacom Middelburg and Witbank services sucks

Vodacom is pathetic Firstly they sue my husband for a contract he didn't open in 2014 for 6 months, my husband paid the amount and sent emails to the ***** unit in Vodacom,it's 3 months and still nothing is done Then he upgraded my phone in may 2019, I got a "promotion" phone, hauwei pro 30 with a watch, I am still waiting for the watch, and know they for no reason blocked my phone, it's a week and it's still not unblocked, nobody can help and tell me why my phone has been blocked, Vodacom in Middelburg mall's service are pathetic, Vodacom in Witbank Highveld mall's service are more than pathetic, and customer care's service is worse than pathetic, I want to know where can I take this matter to,
