Why do I have to to beg you to sell me something??

I have been trying to get a laptop contract out of Telkom for the past month. At the Clearwater mall they have 2 branches. At the smaller branch I was treated like ****. The lady that was supposed to help me actually shouted at me so I walked out. At the larger branch they said I qualify but that they do not have stock. They promised to call but they never did. I contacted them myself but after 3 calls and even an sms that was ignored I got nowhere. I then phoned the call centre today. Guess what? Every agent gave me a number to phone. After talking to 6 (that's right, SIX) different agents and hanging on the line for a total of an hour and a half-I kid you not- I was given ANOTHER number to phone! I have had enough. All I want to do is to buy something from them. Why do I have to beg?? I am asking with tears in my eyes, so please tell me? WHY DO I HAVE TO BEG???!!!!!!!! Please help?
