Bought wireless smoke/heat alarms from Wigan Branch delivery was slow but no fault of there's. However the heat alarm would not come to life, I phoned three times to seek advice and was cut off three times, next time I still could not speak to the section I wanted but was assured he would email them and arrange an urgent return call. Five days later still no call with advice. Same day I emailed the branch again no response. Fortunately I resolved the sticky switch myself so help no longer needed. This is shocking after sales treatment and will look elsewhere in future.
