False quote for S6 repair

on Tuesday 5th Jan i took my phone in for repairs for overheating, restarting and freezing. i then get a quote for R3500 coz u have supposedly found liquid damage (B.S). in the beginning of December i email Samsung direct about my phone freeing (which they never got back to me about then again 3rd January as still no reply). the freezing stopped when samsung relesed a new firmware. now u are claiming my phone is water damaged i would like proof of this and if so a second opinion (if it has to be outside of Samsung so be it) but this false quote for R3500 for something Samsung did as per the 1000 other ppl complain about the same problem and the 120 ppl that were in the Que at the Samsung branch waiting to get their phone repairs and as per the lady that helped me comment \i dont know what happened to the S6 but ever since the 1st we have been crazy busy with ppl bring the phones in for repairs". prior to bringing in my phone i did a factory reset and new software and nothing. i can 110% assure my phone is not damaged from liquid damage. ur 1 year warranty is false advertising and im still waiting for the manage to contact me from the Samsung roodepoort branch."""
