Rude Staff from incredible connection in Gateway Mall in Umhlanga

So My Husband purchased 2 Iphones 13 from incredible connection in Gateway the contract was R900 plus R400 insurance. On the first they debted the right amount and the second month as well when it came to January they took an amount of R4000 with no explanation on why they took that amount we than went to go and ask about this than they say we ask vodacom as they. are the service provider when we get to the Vodacom shop they say they can't even pick up the phones on the system. Mind you when we brought the phone no slip or proof of purchased was given they only gave the invoice with the value of the phones the Manger there was so rude his name is Nazeer Suliman he didn't even want to assist us he told us to go report this with the Ombasment and report it as he won't assist we than wnt back and forth with this issue going to vodacom and them stating that it the incredible connection guys must help us when we inquire to the incredible connection they tell it a vodacom issue .there was a bridge of contract here and no one is explaining to us why they took that much the staff at incredible connection were so rude and unhelpful they didn't even want to reprint the slip that we wanted.
