I am letting out a small flat. It has a built in gas hob in the work surface and a microwave oven. A tenant moved in a month ago and part of the terms were that they wanted an oven fitting within 3 weeks. The property is fully managed. I went to John Lewis before they moved on and ordered an oven to be delivered and gave the property manager the delivery date. I also informed the property manager of the fitted hob and said an engineer/ carpenter would need to go round to remove that and fit the new oven. This is all on emails. I gave the manager all the order details.
The property manager called John Lewis and changed the order for another date to suit the tenant (fine). John Lewis tried to make the delivery for the new slot and neither the tenant or the manager was there to receive it so it went back and was a failed delivery (I don't live near the property).
In the meantime the property manager called me and said "oh there's a gas hob there we can't fit the oven!" I was baffled as we had had this detailed conversation over email about the issue.
The cost of the oven has now been refunded to me by John Lewis as the property manager told them the appliance was not suitable as it had to be integrated 
AIBU to just buy a decent table top oven and forget trying to fit a full new one when there is a fully working 4 ring gas hob and removing that and fitting a new oven in its place has become a total nightmare?
