Disappointing service from Dstv customer service call center

I'm really frustrated and disappointed with the Dstv customer service call center. I have been trying to get them to fix a problem whereby I have been having problems in renting Box office movies but I never receive the movies. I rented Frozen 2 last week and never received it, yet was charged. I phoned yesterday and spoke to Nosipho and I was on the phone for 27 minutes, after trying for several times we were still not able to resolve the issue so she said she'll escalate it to Box office directly and give me a call back, I'm still waiting, I phoned again this morning and didn't catch the lady's name, I explained my situation all over again and after not being assisted satisfactorily and getting increasingly frustrated, I requested speaking to a supervisor, she put me on hold and it seems that she was being deliberately spiteful and kept me on hold to the extend that I dropped the call, she still hasn't returned my call.
