Refusal to replace battery under warranty 18 Feb.

On 18 February the Battery Centre refused to replace my battery which was still under warranty, claiming that it had been tampered with because of a tiny dent on the terminal. They also expected me to wait there for 6 hours while they charged it, even though it was fully charged. ( I had it checked at two other centres.) Initially they tried to hide the test result from me by talking around it. They also stated falsely that 'an alternator does not charge a battery '! ( Also tested at different centre.)
