had a muppett (one of many lately) replace a pump on a combi then left and told me job done boiler upa nd running . turned out far from case put pump in boiler still never worked but told me otherwise . As i was totally unaware had a bill come through for part gone to recieve payment and cust says no not paying as it never turned out to be pump . Can i take this part back or is it non replacable item ?
