Driving School - Bad service

I bought a groupon voucher for diving lessons from Rollingstones Driving school.<br> The 1st lesson was only 45 min, The car had No L- Learner driver sign, the car had no dual pedals.<br> Don't know if the instructor was qualified.<br> <br> 2nd Lesson no one pitched. Called the driving school to arrange for the lessons.Driver did not pithch.<br> <br> Called owner, said he will check his roster & come back , still waiting.
