Disgussed and dissapointed with buying a house through Grosh properties

We bought a house in 2019 through this Real Estate Agency- but Remax was also selling the same house. I had a Remax advisor approach the Grossh Properties agent to let them sell to me, but the agent did not want to. Since living in the house i realised why this agent didn't want to let go and wanted us to buy the house through them. She used her own Beetle inspector who signed off the Electrical work and everything else, We bought it for over a million and still fixing up - used about over R500 000 now. be careful of this agency and the main was rigged. Council slapped us with a letter in the first week of living there - the stove was wired up incorrectly - garage door broke the same week. house rained loads of water during the first rainfall. lost with words... Be careful - and still fixing the house -- Agent was emailed numerous times i phoned the bank and they ignored me too..Bank sells houses so I might take this further after 5 years of hardship- spending so much extra money. struggling.
