On Trip to Exeter yesterday stopped at a Gridserve charger on M5. There was another car using the CCS so plugged into Chademo. It should have automatically switched over when the other car finished, it didn't. Eventually after several attempts it accepted my card and charged, I have to say quite quickly. Checked my account this morning found payments pending for total £56. It appears that every time I presented my card it ring fenced a payment 3 payments of £12:50 and one of £20 This also included a charge on the way back at EH. I nearly had heart failure, I have no idea how to contact them, can't find a contact no. Just hoping that they don't decide to take the payment. Will know tomorrow.
