Bad Customer service

I was called last week and offered a dstv explora which I accepted. I was never sent a 3rd part form for the delivery which I then had to call through and request yesterday. This morning i called Onair and advised them that i received a message that delivery will be done today and because of the form been sent late I haven't left the required documents at home. I spoke to a lady Christina who was rude to me refused to call the couriers saying i need to do it herself and after that just kept absolutely quiet on the phone when i was talking to her. I then called back and spoke to Michelle who advised the managers are not in. I called later again and spoke to Sandile who said he will get a manager to call me and up to now still no call. This is a bad customer service and i actually called back now to cancel this contract as i am shocked at this level of customer service especially due to the fact that i was called and offered this and not the other way around. It clearly seems the employees and managers do not take clients complaints seriously they must have too much business that losing one customer is not important.
