Domestic industries Geyser installation

Domestic industries 28 Peter Rd, Springfield Park, Durban, 4091 had installed my geyser in August of 2019. Due to shoddy workmanship the geyser began to 'fall' literally moving away from the wall. I have called this company approximately 36 times in 10 months asking it be sorted and to this date nothing. Finally my managing agent has sorted out the issue with a different service provider. Domestic industries after sales services are poor to non exist ant at best.
