A good experience let down by poor delivery
I chose a heat pump that was a good product and a very good value deal. I needed the unit to be delivered at a particular time, as I live in a place where delivery is difficult. I therefore arranged for a neighbour to take delivery of the unit and store it in his garage for a few days. I also booked an installation engineer to come a few days after the delivery date. The website told me that the delivery timescale was 3-4 days, and I even checked on the website's Live Chat that this was correct. I waited to order the unit until the delivery date was right for me, then made the order. I found the ordering process very easy.
The problem came when the transport company DB Schenker got involved. I could see from the tracking that GrupoSumi despatched my order within a few hours. However, it then did not move from Schenker's warehouse in Barcelona for more than 2 days. This meant that the delivery was 2-3 days late. I was very annoyed because I had already taken a day off work for the projected delivery date, and I ended up spending many hours trying to chase the delivery.
Whilst the problem was with DB Schenker, GrupoSumi should reconsider giving such short delivery timescales on their website. Had the delivery time been 7 days, I would have been perfectly happy. But setting customers a very high expectation and then failing to meet it is not good for customer satisfaction.
