Lack of telephone service and promotors harassment

I had not even set foot out of my car and the promoter of some cleaning product started to nag on and on about his product and continued to do so after I said that I am not interested. I simply wanted to get some energy drinks from the store and he continued to harass me with the product. Out of despondency I wound up buying this **** because he would not leave me be!!!! I am a regular customer at this establishment and this is not the first occurrence. when I tried to reach engine highveld west per telephone, no one answered. I called 5 times. If this is the service I receive and if I am to be harassed every time I set foot out of my car, I think I will take my business elsewhere -- and I'll be sure to warn the people i know as well.
