Vodacom contract that i signed off for 200, but now they debiting 438

Morning am very unhappy with Elite Mobile which falls under vodacom as they say . I got a call on the 25th of May by one the Sales Consultant which her is MAKHABHIBIB and that indian lady sold a phone which was on special for 189 ,which led to a total of 200.00 which i was with , then agreed upon on paying 200 every month . Which was then debited on the 29th of May. June the 30 an amount of 438 was debited by vodacom . when i ask what was that for , it is said i also agreed to another Sim card which had value added Services which i did not agreed upon or sign for . Now am really stuck with a debit order of 438 which did not sign for , And i called upon twice to ask for cancellation of what has been added without informing or consulting me . Please assist as my request to listen for the call i got on the 25th of May 2021 and help to cancel all added value services which i dont want , and did not request for . I really cannot afford 438 for a fone as have 5 kids . The saddest part of it is that i keep on talking to one Sales person by the nme of Veronica who does nothing at end of the day.All i get rofm her its empty promises and still insisting that will be paying 438 ,00 every month , while she promised for the first time that my query has been escalated and will be resorted
