I would always give the person I am ringing some consideration - there is no way I would ring anyone on a Sunday for a trivial matter.
Bad leak of water, any oil leak, heating stopped in cold weather (or with elderly or kids there), a sole toilet not flushing in a house with more than one occupant, then fine, but not a stranger on a Sunday asking for me to come and quote for a new oil boiler including system flushed and stating she has already got a few prices! I didn't bother as I reckoned I already disliked her without ever meeting her.
I also do not like texts coming on a Sunday that aren't important.
