Roll on lawn failure

I had a new Roll on lawn laid in December 2015 by [URL Removed] During the first month the lawn grew nicely and looked very good as it was still in its own sods. The lawn was watered daily as per instructions and mowed to the required length as specified. In January water restrictions were implemented and the lawn could not be watered every day and subsequently the lawn started dying. On a section of the lawn one could clearly see the lawn died on the sods. I contacted Mr. Russell for advice and he was adamant that the lawn should me watered everyday regardless of water restrictions and also said the lawn was cut too short judged by the photo I sent him, which is not true, I maintained the specified length and he also said the grass is not dead and will revive after watering. I decided to take a chance and water the lawn twice a day, but the grass kept on receding with notable dead patches all over. I contacted Mr. Russell again and he again replied the lawn is failing due to water. Not once has Mr. Russell offered to come and access the situation and recommend a method to save the lawn he kept on indicating that the fault lay with the way I maintained the lawn.
