Bad customer service

On the 31st of July I got a WhatsApp from rain telling me about the loop I requested a call back and an agent called me back.i asked how much it is as it was saying R425 on my WhatsApp and it said save R200 he told me that wasn't true and the add was misleading I asked for the price and he said 675 asked him since I have 101 what must I do he said he will send me the R1 link and cancel my 101.i noticed that my 101 wasn't cancelled until I did it myself and was told it will be cancelled on 1st September.I have tried contacting rain but was on hold till I ran out of airtime,I have requested several calls backs and no one has called me back,I have spoken to Sam the bot who transferred me to another bot with an L name who told me I will be billed twice this month.Rain can you cancel all my plans with you as your service is very poor.Why wasn't my 101 cancelled immediately since I have the loop.if we don't pay you know how to stop the services but when doing a upgrade that you offered you want to charge me double?
