Sorry to use this place but I need some advice. We held back last payment to the ID including a payment for a supplier of the ID ordered from as they have yet to completely rectifying a issue. Starting from top, this was last year end. We were promised the complete reno within 1 to at most 1.5 months (1 room, 1 kitchen). Many thing were overpromised, underdelivered. Putting that aside, we were fine with most of the thing including mistakes of colour and design that we just accepted. However there were issues that were mostly solved by the ID's partner (after a big argument, the partner took over and we made it clear we will pay everything when things are settled.) except for 1. They did not resolve it nor contact us till recently again to chase for last payment. Just not long, they got the particular supplier to get the payment from us but we rejected saying that the ID should be the one solving it. And since 1 issue had yet to be resolved, we didn't think it should be our problem. Moreover they dragged nearly 1 year. So do you think we should just ignore the chasing of payment? Should we go to Case or court? If the ID agrees to fix the last issue should we accept since they already dragged about a year? If the supplier call us again what should we do?
