Will not use again

I called for an emergency situation late at night where the main council feed started arcing and sparking at the connection box going into my home. Lourens answered the after hours number and assured me that it wasn't necessary for an immediate callout and that he would be there first thing in the morning. True to his word he was there with his team 7:30. They sorted the issue within half an hour. They were efficient and his team very polite. I felt the R2735 fee was overpriced for the time spent and work done, but they had responded very quickly and sorted the problem so I wasn't going to complain. My issue started when he called TWICE an hour later inquiring why he has not yet received payment. I stated that we logged a claim with our insurer and that they already confirmed that they would settle same day. He refused to accept this and said he does not work this way and it is strictly COD. An argument started which I didn't feel like pursuing so I told him I would do an immediate EFT and proof of payment and that was that. I just felt as a business man myself that this was very unprofessional. You don't start chasing your payments an HOUR after the work was done?? Sad to say but I will not be doing business with them again.
