Wren Kitchens complaint: Installation team disaster

I ordered my kitchen in April and was told it would take 12 weeks to fit. The installation team assigned a fitter, but a couple of weeks before installation was due to start, I was told that fitter did not work in my area and as a result I had to wait another 12 weeks for installation by another fitter. The installation team did not inform me of the details of the new fitter until after he had contacted me directly and given me the new date. The kitchen was fitted without any problems this week. I received an email ing the tempting date as 17th Nov, but my fitter asked me to change this to the 18th, to be sure the job was complete beforehand. I did this and received ation of the new appointment. my fitter was contacted by Wren to the kitchen was ready for templating and he agreed it was, then later on the 17th I noticed another email ing my tempting appointment for the 24th Nov. I called first thing on the 18th to find out what was going on. I was informed that the installer had called to change the appointment, but it later transpired that it was the installation coordinator who had done so, without any consultation with me. This has now resulted in a further delay in completion of my kitchen. I am totally dissatisfied with the whole process of dealing with Wren and will certainly not be recommending them to anyone.
