I would give 0 if I can, worst service online and over the phone, they don’t explain or don’t know how to explain and just try to make money by lying to customer and get me into the worst situation and charge me excess. Gas got turned off by their phone call to emergency service who came switched off the gas and had to phone them to connect again by paying excess because the staff said if I don’t pay no one will come to connect my gas, if they told me emergency service will not sort my expired alarm out but just switch off the gas I would not have let them come, I could have called my electrician check the alarm and sorted it out in minute and 5 pound, telling me they can came quicker but kept give me later date on confirming when I have no choice as gas turned off. I made complaint while on the phone and just had an e mail saying that they closed my complaint without telling me what is the outcome, then I saw an invoice charging me the excess. Basically they ignored my complaint. Hours on the phone and it was hard to get through by machine talking. Awful.
