Poor service

I’m so disappointed with the service iv received from cashbuild (Zebediela, Moletlane branch) Iv bought a geyser and it was installed by a recognised plumber. After few weeks after installation they geyser started licking and electric was trapping every time we switch on the geyser. I laid a complain with the store manager and he promised to sort it out, now when I contact him Iv been told that the manufacturer people which is Gap geyser they not responding and they are the only people who can fix it. It’s been 3 months now since Iv reported the matter but I’m yet to receive any call from cashbuild or gap manufacturer.

The manager responsible at cashbuild zebediela branch is Mr Maponya. Geyser serial number M***

My contact number is +***.
