Unprofessional after sales service - no action to remediate deficient workmanships

In 2024, our complex required a large section of our ageing driveway to be re-paved. Style & Craft was selected as the contractor, and they re-paved a large section at our entrance/exit gates of our complex in October 2024. In late Dec 2024, we contacted them regarding a section that they paved in October, that was subsiding and that had to be remediated. Understandably the construction business was closed over the Dec/Jan holidays and we settled in to take this up again in 2025. There was a bit of ad hoc delays by both parties, with trustee movement/ contact people / availability changing etc. But all parties met on site in May 2025 and the concerns were raised with the owner, the salesperson and the actual contractor used in October 2024. Since the meeting in May 2025, we have not heard from Style and Craft, despite several mails and phone calls from our body corporate to their offices on a fairly regular basis. There has been no contact whatso ever from their side after the May 2025 meeting. This is so unprofessional and unacceptable, considering the amount of money spent on this project in 2024. I would expect this behaviour from some fly-by night operation, but not from a company that has been around for so many years and bragging as being the oldest existing member of the Gauteng Master Builder's association.
