LG G4 repair

I had taken my LG G4 in for repairs to the repair centre in Umhlanga and explained that the phones battery ran low and i was unable to charge again. The handset was within the 2year warranty period. I did not receive any feed back and had to call for an update. I was told that the phone had water damage. I insisted that that was not the case and asked to speak to the manager . the manager gave me the same story and refused to accept what i was saying. They even sent me pics saying that the phone had water damage and that was the reason it was not functioning. Since then i took the phone to another cell phone repairer who fixed the phone in less than a hour confirming it was the charging pin that had to be replaced. Extremely disappointed with the service received and will certainly not be renewing my contract with Vodacom.
