yer mate, can see the rusty/dirty bit of old snapped off coil preventing the new coil from sitting right, i also think it could be upside down, the more coiled end of the spring should be sat on the lower arm, the less coiled end should be located on the chassis
get it back to where ever you had this done and drive slowly, thats dangerous as **** mate as the spring is not seated securely and could become dislodged when hitting bumps etc at speed
