Poor out of hours support

I recently had to contact Andrew grant property services on a Saturday due to boiler issues. Three telephone calls and an answer machine later and I obtained a mobile number which, also went to answer phone. The message asked politely for my details where, within the hour someone would return my call. I waited patiently ........for 2 days before Monday morning came round and I was forced to spend the weekend without heating. Natalie answered on behalf of property services and, to her credit got everything instigated for a call out. In short, Natalie was brilliant but the out of hours support is a failure. Other dealings with Andrew Grant to date are fine.
