Worst call centre experience

I tried to upgrade my package via whatsapp. Only to find out that a 2nd subscription was added to my account without my authorization. I called to the call centre and the lady told me she was transferring me but rather placed me on mute for 10 minutes and then dropped the call. The most frustrating feeling when u are already being charged a high monthly rate for **** channels, no wonder people are canceling dstv for Netflix and other options. I want the 2nd subscription cancelled and only have my 2 extra views
