Bought a free standing cooker and fitting - provided both AO and Expert Logistics with the required dimensions to ensure a smooth installation. Upon arrival the fitter refused to install the product, and cited a hot zone clearance not being fulfilled. Order cancelled. Upon closer inspection (and clarification from the manufacturer), the fitter had misread the diagram and there was no reason not to install. Spent an hour with customer service - trying to explain their mistake, to see whether we could rectify it today (to avid taking another day off). Unsuccessful. Won't ever buy from this retailer or installer again. Utter shambles.
