Town Fair Tire Centers review: installed wrong size tires

I went to Townfair Tire center Which is available inNashua .They installed wrong size tires, but upto now I don't know whether they installed good size or not .But yesterday when I went to anthor tire shop they told that you people install wrong size tires .So Iam facing difficulty due to wrong tires and also Iam filed complaint about Compensation for these wrong installation .
Please change my tires to good ones .
