Rear suspension/ESC issues after spring replacement?

[StephenQ5]

18 plate Q5, so just over 5 Years old. At last dealer service they said it needed 2 new rear springs. Got these fitted by an independent garage at less than half the price albeit now wondering if that was a mistake... When car goes over a bump it seems to wobble at the rear and doesn't seem to hold road well. Get same - which is quite unnerving - when driving on wet roads (in the greasy sense after rain has falled on a  dry road and not dried up yet). I wondered if there was some problem with the suspension or Electronic Stability Control. No warning lights on at all and otherwise car is well and has passed MOT after the springs were replaced. Any ideas?.... (wanting to see if anyone has any input before I take it back to the garage that replaced the springs). TIA.

Hi are you sure they got the springs the right way up and both top and bottom fittings are located on the rubber mounts properly.
