I’ve had an account for over a year but only have had to use it twice. On both occasions the app wouldn’t recognise the charger so had to use a contactless card and the higher amount per kW. On the first occasion I found my bank had been debited £15 by Chargemaster for a £4 charge cost. After phoning and complaining the balance was paid back a week later. On the second occasion 5 weeks ago the app again wouldn’t work so had to use my card again. The first charge started but failed immediately. I tried a second time and had a successful charge, costing £4. This time my bank account was debited £40. I have emailed the Pulse help agent 3 times and still no refund. I see Trust Pilot gives Chargemaster a one star rating and I quite agree.
