Charging block not functional

I have a S6, had it for two months and then it stopped charging, I first thought I was the charging cable so I bought another cable. Didn't work. Took my phone into the Samsung repair Centre close to Hilfox Centre and I was told that it is repairable but wouldn't be a warranty claim as it is as a result of malicious damage that my charging block doesn't work. I find this highly unlikely. I was told it will take between 3 - 5 working days to repair or get a quote. I asked for an approximate cost and was told around R1800 I use my phone for business purposes. it is the only phone I have so I cannot be without a phone for I do not feel I need to pay for the repairs to this charging thing. I have been using my charging disc that came with the phone for months now and I don't feel I need to be inconvenienced like this. I have sent an email to Samsung Cares with no response. So I hope I get a response of sorts now...
