Pass With Us Driving School

This company hasn't responded to any of my calls. When i finally got through to them i was told i'd be called back by and instructor in a few hours, weeks later still nothing. So had to contact living social again (who i purchased vouchers through) and they had contacted pass with us again on my behalf, gave them my contact details AGAIN. Monday 16th april i got an email off living social saying pass with us have said they would contact me within 2 working days, 21st april and i still have not been contacted. I purchased these vouchers about 3 months ago. I've phoned pass with us main contact number about 6 times now leaving my number each time and also left it on the mobile number i was given, still nothing. Not professional at all!!!
