Disgusted by people who get jobs and can't even do it

We rented a movie on Box Office called Trust and to our surprise the movie was not full and just ended in the middle of nowhere, we left it to check the next day but it just disappeared, we called in and we spoke to Sandile who told us he can reverse the money for the previous rental and then we can rent it again and that was done, we fast forwarded to the part we watched but it still did not play till the end, I called in again and spoke to Luthando and he said there's nothing he can do and that they cannot reverse any money and that Sandile cannot do that and that the previous rentals money is also still outstanding which means that we have been **** to and cheated, he said we should visit the website so that we can get assisted, so please tell me why the hell there is customer service if they are not going to help, we should the rather use the internet and data for help and still we wasted our damn airtime speaking to illiterate people who aren't able to help when they have every resource available to do their damn jobs...this is utter bull**** and if they aren't dealt with appropriately then you guys are hiring ****
