BP Botha Electrical PROVIDE NO WARRANTY on their workmanship and they use the CHEAPEST materials

A year ago I purchased an apartment, and BP Botha Electrical issued the Certificate of Compliance (COC). The electrician replaced several electric items (inter alia he added an additional wire to the geyser to make it safer and as a result had to replace the geyser's circuit breaker in the main switch board to a double switch). Within a year this NEW switch got damaged and had to be replaced. BP Botha Electrical refused to acknowledge or reply to my emails. However, they responded to a WhatsApp message and confirmed that I used the correct email address. Long story short - I had to pay another electrician R1050-00 to fix the faulty switch. The new electrician told me that BP Botha Electrical used the cheapest (and poor quality of course) circuit breaker available on the market. PLEASE DO NOT MAKE USE OF THEM AS THEIR WORK CARRY NO WARRANTIES.
