rudeness,arogant

we recently opened a new restaurant in gail street and we asked the printroom company in umbilo to help us with our signage and the menus,for the past 3 weeks we have been waiting for the feedback and we didn't not get any response we did pay them in full but we never got anything back. We ended up getting hold of the owner Colin and Trivesen but they were also rude and they didn't submit our signs in time and when we tried to speak to Colin the owner he was also so rude and arrogant and he said he has been calling our company but no one answered of which when we asked him to tell us which number he was phoning, he didn't have the number and when he came today the signage was not right and we had a meeting with him from 8 to 9 but when we got there he was so rude and arrogant and the signage we had told them to fix was not in order at all. Their company service is very bad all the time when we call them we wait for more than 10 minutes before someone comes to help you and still nothing get sorted out at all. and we thought including the owners would make thing better but even the owner Colin is even more rude and had a bad attitude and we did pay a full amount aswell
