have a problem here with someone who installed a house alarm in my house. he came highly recommeded from a friend and at the time i didnt ask for a receipt/invoice. the alarm worked for a while and then it started to go off in the middle of the night. i rang the person who installed it and he asked me to try it once more in case it was a once off. i did this and it still kept going off. i rang him again and he was always too busy and kept promising next week....... to make a long story short my friend told me he was going to the U.S. for a couple of months and i tried to get him and i kept getting the same old story but i was promised that he would get back to me befor he went. it has now transpired that he has gone and i rang him left a message on his hpone and he has sent me a text telling me to get lost. Were not talking about a lot of money here, its only a matter of principle but has anyone any ideas of what i could do?
