Pennypinchers Kempton Park - Terrible service..

I was at PennypinchersKempton about 2 weeks ago to get boards cut for cupboards, and Indian gentleman named Shawn( don't know if this is the correct spelling) helped me and promised to get back to me with my invoice the next day as their systems were off. I called the next day and he told me he is busy with my invoice and will send it shortly. I tried calling and to contact him ,left messages for him to call me back.No response from him and it is now 2 weeks later. Terrible service by this man .
