New windscreen - now interior needs a valet

contacted Glasfit Alberton to replace windscreen. Booked for off premise repair on Wednesday morning early..Later in the morning was told they had no stock of screen. Waited for them to come in the afternoon, but called at 16h45 to say screen only just arrived. On Thursday came to my house to replace screen. I complained about loose exterior trim which they fixed but now the inside of my car is covered in black fingermarks and stains. Not impressed. Last screen was done by Glasfit Bedfordview. It leaked and one side did not heat up any more which is why I dint go back there. Guess its PG next time.
