I received delivery of my washing machine this afternoon and paid yourselves to install it which the two men did and left saying everything was good. I subsequently put in a small wash having read and followed all the instructions. About 7 minutes later the machine started making a terrible noise and started jumping uncontrollably out from under my worktop across the floor. I subsequently discovered from looking at the rear of the machine that the installers had failed to remove one of the delivery bolts!!! What totally unacceptable service this is and having paid for a professional instillation I have not received the required service I have paid for. It also states on the Samsung manual that the machine MUST NOT be used without removing these bolts as it will damage the machine!!! I now require a new replacement washing machine and compensation for the breach of contract in providing an inadequate service. My order number is 1440147.
