Non Response to poor workmanship issues

In late 2014 we employed SPS to refurbish our pool. This involved cutting, rebuilding, relocating in and outflows, relocating light, relocating the electrical and filter unit and laying a new tile surround..... a new pool. The total cost was significant. <br> On completion there were some small snag issues outstanding, but we reluctantly paid the last 20%... extracting a promise that whatever issues remained they would be promptly dealt with. <br> The snag list includes an electrical concern at the pump switch (you get shocked), cracks in the paving grout, area of poor drainage on the paving, a small leak at the filter (the old filter unit was installed).<br> It is now mid March.. despite many phone calls, sms's and emails .. and many empty promises, it is incredibly difficult to get any action on these items... appointments are made and broken... etc.<br> Don't pay the installment until you are 100% happy.
