Chamberlains Strubensvalley !!!!!

Be careful when purchasing from Chamberlains Strubensvalley. Yesterday I purchased a lock for a pivot door that was faulty. Today I take it back. The salesman tells me not to tighten the bolts on the cyllinder, and to put locktite on. When I told him that's stupid, he eventually gave me another lock. We then had to go to the Information counter. I had the incorrect Chamberlain slip. After 20 minutes they still couldn't find the lock on their system. I showed them on my bank statement the details of the transaction. Then a manager came and still couldn't find anything. It was a straight swop. Faulty lock for a hope not faulty lock!!! I just started a complete renovation of a townhouse. Guess where I WON'T be shopping again.
