Bought a new doorbell from the always friendly and helpful staff at your Christchurch branch 206861 door chime which we duly installed and selected our chosen bell tune. It transpires our neighbours have a similar bell which, when pushed makes our bell ring and vice versa, which is quite hilarious. Luckily we are friends and have selected different tunes so know when it is a false alarm excepting the other evening when ours went off and they had inadvertently changed their tune, giving the impression that there was a pack of nasty barking dogs in our hall! Fortunately we realised what had happened despite being a little alarmed by the prospect of a pack of wild dogs in our hallway. It did make us have a good laugh and we wonder what sound will greet us next time our neighbours doorbell gets pressed, so thanks Robert Dyas for the laugh.
