Overcharged subscriptions

I am very frustrated, ****ed and very angry at vodacom their consultants were busy calling me non stop around january to february telling me that they want to migrate me to a better data bundle package which automatically changed my premium by a R30 something and i my account was on top up that time then i started to notice that my statements were showing huge amounts i need to pay for my vodacom only to find out a month later that my package had been changed to open line without my permission no consultant informed that by the time they migrated me my account would be an open that what makes so angry because i feel ****** and ******ed now i have a huge bill that i need to settle of a total of R2800 with arrears amount of R1400 and there are so many subscriptions which were added on my account which i wasnt even aware of and which i never asked for them to be added as extras and all of those subscriptions keep on adding to this bill what ****ed me off the most is that customer service told me that they are unable to remove all these added subcriptions until i settle the amount in arrears and i dont have that money i am just so stressed because i also have other expenses that i need to take care of, i am really dissapointed at vodacom i regrett myself for even allowing them to migrate my data plan if i knew that i was going to be overcharged this way
