poor service and bad attitude

I took my phone for fixing to sumsung in richardsbay on the 30 the phone was still under warranty so they said they will not charge me anything..and they said I should collect it after 4 days but till now its not fixed..when I asked why they said I rejected the quote of which I don't know about.when they called the people who were supposed to fix it, it was found that I was confused with someone else, they actually called someone else annd not my 2 numbers I gave them..I waited for them to try and solve the matter but they never paid any attention to me they continued with other customers as if I wasn't there, mind you I've been going there to check on my phone but they never said anything about. the quote....what is happening with sumsung?I am very angry
