Bought Sony M4 Aqua poor poor quality

I bought Sony M4 Aqua from FNB and I have only had the phone for 2 weeks and already the Phone is not charging. Took it to Sony vodaworld Midrand and was told that the Charging port is faulty and I need to take it to Boksburg in order to get it fixed. Just when im still dealing with that shock my friend tells me she had Sony Experia as well and it was not charging they had to Fix it 3 times until she gave up and bought herself universal charger. which is a problem for me since the battery is built in I can not use universal charger. So annoyed right now, Wouldn't advice anyone to buy Sony Phone ever. ....SONY Sells poor quality phones
