Vodacom doesn't comply to their own deals

Upgrade my contract did the upgrade online deal is for a Samsung A52 5g and a 45mm smart watch and 50 min talk time and 500mb data for R299 per month. Now they deducted +-R6700 for the smart match but it was all included in the deal I have screen shots of the promotional deal and when the call center phoned me to confirm they didn't mention any additional pay ins. Now my debit order wil not go through as they are supposed to becouse Vodacom deducted this insane amount meaning that I wil get a bad credit rekord for someone else mistake. I phonend them all they can say is that I have to wait for seven working days. Now that's not helping me how are they going to fix my credit score?
