no service at telkom silverton

a phone i purchased at telkom silverton in october 2014 has a problem with the speaker and today i come in at telkom finally because their operating hours are rubish and they tell me they have to book it in for two weeks which i advised its unacceptable i either want a interim phone or my money back, and i spoke to some manager from centurion branch whom he refused to give me his name and was absolutely rude, who told me they wont help me i must go to their website and read their terms and conditions, but wen i bought the phone no one told me of terms and conditions, in drsparation insisted i am not leaving until someone helps me and they just avoided me and were not even bothered, i have never experienced such horrible service and i must say u dont inform customers then make it their fault that u such a retarded institution i waited for an hour with no one even making an effort to help me but wen i camme here last year to buy a phone it was so quick transaction done in 5 minutes.,, telkom is disgusting to say the least
