VODACOM!!!!!

I am struggling to get my account at Vodacom to be corrected sins i upgraded my contract phone and my sons phone in February 2020. I have 4 Cell numbers on contract : 1-myself ***x8287 smart+. 2-my Son ***x9745 u Choose Flexi 230, 3- my daughter ***x2924 uChoose Flexi 390 and 4- my Data Line 2Gig. ( NOW UPGRADED TO uChoose flexi 175) When i upgraded the two phones on line, Vodacom used my data line ***x9649 as a phone upgrade and instead they did NOT upgrade my sons phone as i requested now i am paying for 4 phones on my contract where by i only have 3 phones and 1 data line (2G). When i started to do my 1st inquiry i was told that i MUST convert the airtime to data "HOW IF THE SIM CARD IS IN MY WIFI TOGGLE".or "I MUST GIVE MY PHONE BACK" """WOW""" NOW where i normally paid R109 for 2 Gig Data i pay R499.00 for approximate 1.5 Gig???? I made inquiries now 3 times but nothing was been done til so far ""NO CORRECTIONS, NO FEEDBACK, NO NOTHING""All still the same, but every month from April since the upgrade, Vodacom collect the contract payment via debit order, MORE and MORE each month for WHAT. I do not or use any over and above on my contract and DATA line (WHICH I CANT USE). FIXED PRICE and FIXED TIME PERIOD example R300.00 X24 Months"""WOW"""but increase every month from anything like R1999.00 to last date July R3162.00 and then R2750.00. by now i got over debited for what?? STILL WAITING FOR ANSWERS 1st inquiry: Received no feedback. 2nd inquiry reply: Good day, Please see feedback below from Retentions. Client received a device with the upgrade K*** & its over 14days. Upgrade cant be reversed. Lockdown was end of March,client received K*** for cell:*** early Feb.We cant reverse it! I think the best option, customer must convert airtime to data. SR closed from our end. Kind Regards 3rd Inquiry I was told they would forward my inquiry to higher Authority at the on line upgrade section for a review. "NO FEEDBACK" Where do I GO?? But still got DEBITED !!!!!!
