Bad service a d ****

I'm not happy with Dstv internet company last week Thursday on the 26th of September I app**** for dstv internet via WhatsApp chat with the agent I asked relevant questions about DSTV internet of which I needed and I asked the agent if is it necessary for me to buy the router and they told me the router is for free so today I received the router of which I asked them to apply it for me so when. I activated the router it was not working it had green lights and when I check my bill of which it was supposed to be R479 I found it on the amount of R973.83 of which I don't know about it... So now I paid my dstv package of which is R320 monthly and they were going to deduct 179 on my account for Dstv internet now when I call them they telling different story's of I don't understand all this month I've never owe dstv any amount my dstv was always outstanding I have never owe them anything...earlier on I called them about this issue and the lady told me she's going to inquire them of which was extra on my account to the team leader so few ago I called them and the other telling about money's of which I don't understand what she talking about and I asked her to cancel the internet for me and she said she's going to transfer the money to the internet office and she did I've been waiting on the call to answer for 15min until they hang up my call so with all due respect can they please come and take there router of which I don't want it anymore I want afford to pay that R653 that I don't know about thank you
