Non payment

Our company have been service providers for Sure Assist since July 2017. For every job done for them, we have had to go over and above by providing pictures before and after, their job card, our job card and complete a 2 page document provided by them. Since then up to date we have not received a cent. Unless you follow up on payment with no or very little response, you do not hear a single thing. Do not trust these people, we do believe that this may be a plan motive of theirs. Our theory is that they jump from service provider to service provider without payment.
