SMEG bought with parts missing (twice)

My husband and I bought a SMEG built in oven with extractor fan from the Nicolway Dion Wired- we called out an electrician to install it and he phoned us to notify us that the box was open and had no booklet and many parts missing.<br> We then notified Dion Wired and they replaced the unit. The electrician came back a second time and again could not install the extractor fan as a Charcoal filter was missing.<br> When we notified Dion Wired again and they told us that we need to order the part from SMEG ourselves.<br> This was never communicated to us up front and as a result we have incurred the costs of two call out fees for the electrician on top of the opportunity cost of weeks of back and forth phone calls and physical visits to the store. <br> I am just astounded that I had to order, pay for and fetch the part after going through this ordeal with Dion Wired - please be warned that appliances may not come in working order from them and that parts may be missing.
