Pathetic Service Johan Greyling

I made an inquiry on 18 September on a bike I saw they advertised on their website and only received a reply on 20 September from Johan Greyling. After sending him pictures of a trade in I have he never got back to me even after I called him and emailed him numerous times. The last mail I sent was on the 25th September and I have yet to hear from this man. Is this how Bikes4Africa does business? Are they really that busy to turn down a deal? I was very keen on the bike I found on their website but now I have taken my business elsewhere and I will NOT be recommending this pathetic service to anyone!!
