My brother works on behalf of Miller Patterson and this is not the case what so ever. Payment would only be exchanged on completion of the work. I have recently bought a house and had my Loft and wall insulations done. It cost me £348 in total and they did a really good job. The whole message that you have written is completely wrong and infact it angers me that you are giving this respectable company a bad name. Who ever has come round to your house would have not been working for Miller Patterson and if they were would have had id!!!
