Dangerous - Can Cause Injury

I purchased a Samsung S4 from Vodacom when it first came out, I was so happy to be one of the first to have this phone. This phone has been nothing but bad luck to me and I am very dissapointed in Samsung,I dont want to buy another Samsung EVER again. The first battery swelled after only a few months, I took it into Vodacom to check it out, and was told the S4 range has been known to do this and has therefore been discontinued.I was told to make sure I only charge the battery as necessary. I purchased a new battery from Vodacom and followed that advise, but the same thing has happened! It has swelled so much that the battery has pushed the screen up, revealing the inner part of the phone. This is extremely dangerous and I can no longer even use this phone. A consultant at a bank I went into just looked at it for interest sake, and told me her husband had the same problem, only it exploded in his hand!!! I have therefore put the phone in my drawer, and am not using it for fear of my safety! I paid alot of money for this phone, and now I have to throw it away. Very dissapointed and no longer a Samsung fan at all!
