frustrated customer

I was called in April and i was told that DSATV is reducing my subscription from R760 to R378 of which in My and June I paid the revised amount. Today I received a sms from DSTV notifying me that i will be paying R 545 from the 15 of July. I called DSTV and I spoke to Pheziwe and asked her to give me an email address where I can direct my query and she gave me an invalid email address , now I have just spoken to Nompumeleo where I requested to speak to the team leader and she refused to transfer me to the team leader and when I said i will write a review on Hello Peter she said go on and wrrite the review, DSTV cannot make me pay fluctuating subscriptions and when I call the agents they are saying something different, Nompumelelo is adamant that in May and June I paid R 760 and when I say to her I paid R378 she says it is not true and I told her that I have the invoice from my banking app that confirms that I paid R378

I think Multi choice DSTV are reaping us off
