Impossible to get through to Samsung Canal Walk

Handed in new Samsung 6S + for water damage at the Samsung Care Centre in Century City on 23 December 2015. Many days later quote of R 7000 +to repair. Ok so far. Now parts required from Jhb first. Tried to call no less than 20 times today to try and speak to anytime. Could not get through and if one gets through the phone gets cut off. Enough to drive one mad... Really pathetic service - Implement workflow or something else at least...
