Poolright's poor service delivery

On 30/03/2015 we received a Poolright quote from Tyron Frost, for the supply of backfill sand AND to backfill the section around a pool. We were told work would start early on 07/04/2015 & be done by COB 08/04/2015. On 07/04 a driver&2men came to offload the materials. 1worker was left to fill sandbags. All equipment was available on-site to complete the work. The worker left & was to return at 09:30 on 08/04/2015. Randall, foreman at Poolright, arrived at 14:30 on 08/04. No evaluation of the pool backfill area was done during his visit. The said worker arrived later in the afternoon & didn't work. Trevor, Poolright foreman, arrived on 09/04, & noted that no one was present. Thereafter, 2 workers and driver arrived and began working on the backfill, unsupervised. They were to return at 09:30 on the 10/04/2015. Unsupervised workers arrived at 12:30 on 10/04 to complete the work. There had been no quality assurance work done by Poolright at any stage. They began to fill pool and it buckled on one side. Poolright's workers left the failed job on 10/04. We were forced to use another pool installation company to fix the failed job.
