Oh dear I think that it sounds as if your tree is dead. Scrape a little of the bark on the trunk away with your thumb nail - if it is green underneath then there might be some hope, but if not ................
It probably needed more tlc than planting, watering and ignoring it for a fortnight. The weather began to improve in May didn't it? At least it did down here - and newly planted trees need a lot of water.
Did you plant it with straight B&Q compost, or did you mix it with the soil - mixing it is best.
If the tree is dead then I suggest you plant another one in the autumn, that way it won't need as much watering, as the weather will be wetter and the tree won't have to carry any leaves. That'll give it a chance to get settled in before the spring when it has to do some work.
