PUDO has NO customer support for integrations!!!!!

If you want to experience EXTREME FRUSTRATION and risk getting ulcers, try dealing with the company!! I am trying to GIVE them business - I am trying to integrate my website with their courier service and I'm having a problem. Do you think I can get a single person to actually address MY problem? All I get is automated email responses which DO NOT address MY issue!!! There is no number to call, no-one to speak to. Even when I asked to speak to a manager, 'sorry, there is no number for the manager.' I'm going with another company, even if I have to pay more. This is not worth the frustration!!!!
