No service and bad costumer care from multichoice

My name is Buyisile Khumalo I'm a dstv costumer I'm frustrated bcos I saw a internet combo advert on their app and I liked it then I took a contract but to my surprise the combo I saw and what I got was two different things so I tried calling to complain in April then I couldn't get help I was told they'll be back to let me know what's going on but to no avail the following month they debited so I let it go because I was so angry but I called again today on the 29th of June and I wasted 30minutes of my airtime for nothing because I was never helped I'm thrown from pillar to post and left hanging again as the agent said will come back to me until now
