Terrible company to deal with

Really a terrible company to deal with. Donick la Grange promised me a discount but it did not happen, supposedly because I did not accept the discount! After I complained she promised me a bigger discount but this did not happen either. I emailed but no response. I tried to call, but there is no number for this kind of support. Totally unfriendly and ***********. Or is it not incompetence? Maybe rather dishonest?
