Job ref 16530492 name R Dell SM71nz Excellent service as far as repair and quickness in carrying out the repair but I must bring to your attention that I was sold a packet of 3 pack odour prevention tablets for the costly sum of £10 when I was told it will stop corrosion. I trusted the engineer, after his visit I found out these same tablets could have been brought on Amazon for £3.99 including package and postage and just to rub salt in the wound 3 out 4 reviews did not rate the product So I suggest you rethink your engineers selling powers by all means let them make a little extra for themselves but not to the tune 60%
