Do not touch these guys with a barge pole!!! Absolute scam artists, accepted the exorbitant charges based on the fact that we had no choice, my daughter was locked out of her house at 11pm with no other options. My issue is that the cylinder that was used to replace the one drilled out was installed with the key on the inside of the house and the thumb turn on the outside, I don't expect the technician is that dumb, I can only assume he didn't have the correct one on him and couldn't care less. I replaced the cylinder with one that could actually secure the property & asked for a refund for the £125 cylinder supplied. The total bill was £490.80 so I believe that this was a fair request. 2 emails explaining my dissatisfaction & the only response of the technician calling me to tell me that the only option they would give me was for the technician to return & change it. I'd already explained that this had already been done (with a perfectly suitable cylinder which cost £14. Based on reading the reviews of other dissatisfied customers I'm now not surprised. My frustration with this company has now resulted in a quest to inform as many people as I possibly can to avoid them like the plague.
