Terrible Service

I sent my vehicle last September to Chip Logic this year March my car became problematic and as I am still under the 1 year warranty gap we called OB at Chip Logic to sort out the vehicle. From the 15 March 2015 to date the car has not been been sorted out the computer box has been removed but the guy won't repair the vehicle it's 4 weeks and all we get is excuses and lies. Please assist
