They are bad rude people and does not pay

This company contacted us for work to be done on one of their truck freightliner. We went out did the job in October 2023. After numerous phone calls (please take note) to the control room. They can not help the Managing Director does not answer her phone calls. This is now January 2024 and they still have not paid us for the work done. Send emails, whatsapp and again phone calls but no response and no payment was done. Got hold of her husband who is also the director and he does not read my whatsapp either. Today I got hold of him by luck but boy of boy he went off on me and swear at me over the phone telling me he has a lot of companies and that he will make the payment cause he is sitting infront on his computer. His wife read my whatsapp and emails but does not answer me back, her husband did not even to bother to try and sort it out . If you phone the landline to come direct to the control room no direct line to the offices. They are unproffesional and rude. We will never do work for them at all. So who ever reads this please do not do work for them cause they do not pay. Now the vehicle is suddenly standing in JHB and park off without payment for work done.
