The sales lady Lethabo in the parts department is very rude and has poor communication skills

The sales lady Lethabo in the parts department is very rude and has poor communication skills. She failed to keep me updated with my order and I had to keep calling in to ask for an update regarding this matter. The telophonic service is also very poor as you are sent from the reception to the parts department then back to reception, so its just a back and forth struggle on the phone line, when you finally get to parts you are put on hold for 10minutes until the call gets cut. Upon questioning Lethabo about the delay in my order and poor communication she told me that im being difficult! How am I being difficult in doing follow ups on my purchase whilst im well within the time frames provided by her?
