Builders w/house don't care

Bought 3 x25lt paint 10 days ago --only had one tin they told me they would get and phone once received-other two tins 10 days later still ,still no phone call -- I have to do all the phoning-- all centre useless--store no better --north riding -now they tell me they can't get the other two tins --wall half painted --had to send painter away --wasted money - and no senior managers -regional will phone you ---won't be buying paint at builders again --in fact just won't use them ,but with there attitude they most likely don't care
