Picup no longer Picks me up

We have had a Picup account for the better part of 3 years. Initially the service was great and we used their services more extensively. With their growth and expansion the cracks started showing in that "their" drivers, who are freelance, didn't know the areas in which they were operating, loaded multiple trips in an effort to secure more jobs but at the expense of Picup clients and the list goes on. We complained constantly in the hopes that someone in their operations department would listen and attend but sadly this has not happened. Lately they have moved onto a new platform. It doesn't look any different and functionality remains the same but now we do not have access to our invoices. I have tried contacting them via email with no response. I tried calling but none of the numbers they have are working. The frustration has driven me to the point where I would literally move our business to another supplier with a similar service.
