Water falling off patio in wrong direction with no drainage -how to rectify?

EDIT- thank u Dave and L&D landscaping. I will ask our landscaper how he will rectify it. Am I right in thinking that the only way to rectify multiple 4 mm lippage in t porcelain tiles aswell as t water fall being directed forward instead of backwards (as agreed verbally but evidenced by the gravel trap) is to bring up all t tiles and relaid? Is it reasonable for me to say my confidence in a good job being done is now lost and refuse final payment and get a different person to do t job? Thanks, much appreciated. Hi all, we’ve just had a 30 square metre porcelain patio laid at the rear of the garden. The back and side hedges are retained by sleepers 60 cm high due to a top tier being dug out. The agreed plan was for the water to fall off the patio to the back and sides to a 3 in x 4 in gravel trap in front of the 3 sides of sleepers, I did question whether this was sufficient drainage for a patio that size and I was assured it was-is that right? Well we have just tested t drainage with some buckets of water and t water is actually falling forward onto t grass where there is no drainage but even worse as there is a graduated dip in t patio it is pooling to one area creating a puddle at t front lip caused by t edging which then eventually spills into one area of grass. This will cause problems with our lawn. There is also smaller pooling elsewhere due to some slabs being 4mm higher/lower than the adjacent slab. Is that acceptable? When I asked I was told yes. However I am worried about pools of water causing ice in t winter with my young children. I feel t only way to remedy it is to bring up all t porcelain (which will probably break t slabs) and then measure t fall and relay it. Is this unreasonable? I’ve paid half of the total cost so far and t final payment is expected tomorrow, is it fair of me to withhold payment? I don’t hav confidence in them rectifying this and would prefer to get someone else-legally do I need to let them try to do it? If not could I ask for a refund as the cost of getting someone else would b much higher than t money we haven’t yet paid especially as we will have to buy all new porcelain again. Thank you for your responses, it is much appreciated.
