Impregnable, unbreakable, uncrackable security? I found out to my cost that this is not the case having my house burgled and my car stolen with the thieves coming through the Impregnable, unbreakable, uncrackable lock. Upon contacting Rockdoor I was met with total indifference and reference to T and Cs with them stating I must have left my keys in the door which is not the case and was made clear in my statement to the police. They also stated that as I didn't have the lock because the thieves took it that they couldn't conduct an investigation so levelled that at me as the customer to assist their getting out of their guarantee. They then also dropped a shoulder and stated the lock is made by Avocet who will not pay out on their guarantee if they don't have a lock to look at so deflected blame further. On the whole and in my experience their guarantee, their marketing and their claims around the lock are obviously false. I have crime numbers and emails to support what I am saying. My advice would be to be aware of the above and if a purchase is made do not expect any support from the company and total disregard by them for what has happened. None of them has contacted me to establish what happened and they appear to have total disdain for the customer. This also seems to be prevalent in other posts on here.
