Cell C passes the buck and i pay

i have a contract with Cell C which i upgraded in Fed 2015, i used the phone for a few months and suddenly the LCD went black when i took the phone out of my pocket, i took it to the store and they advised if they send it for repairs it will take to long and i should take it to samsung which i did and ever since i have received the worst service from samsung and no word from Cell C. my phone has been to samsung 4 times now since 1st incident as they have damaged my phone and i had to pay for the repairs. Now im left with a contract that im paying for with no phone that im paying for. further to this i had to buy another phone as Samsung phone manufacturer didnt have a loan phone to lend to me. i have had no communication from both providers unless i call in and even then no one knows anything. this is absolutely pathetic and Cell C as i have had to many issue with the service, example two upgrades in a row they could not activate their own sim card. luckily for me i worked in the mobile industry and had to tell them what to do. Cell C you are my service provider not samsung and i should not have to deal with this ****. i want a new phone cause this is ****.
