I've been hussled by a locksmith, poor service and threatened by their employee

On Wednesday the 15 June 2022, I had a bad experience. My house keys broke as I was opening the door. I then called locksmith, they asked for my location. I asked them for a quote and they never gave me. So they sent one of their guys...I asked him before he left midrand for the price and he never gave me he said his prices are affordable . So he got to my house in Kempton park. When he arrived I had already removed the door handles. He unhooked the door and damaged the lock system. After that he sent me an invoice of R1595😭😭😭, I didn't have that kind of money, I asked for my brother and the lock smith guy started threatening me because he could see that I was struggling to put the money together. I said to him I asked you for a quote prior to avoid such and you refused to quote me nor giving me your prices. I managed to raise funds. He left my locking system damaged and never even attached my handles. I ended up asking a neighbor of mine to clean up the lock Smith's mess. Immediately I reported the matter to lock smith and they said they would attend to the matter on the the following morning....till now no one has even tried to contact me
