Terrible customer service - call centre workers with no knowledge who just don't care. Disconnected twice, not called back despite arranging this with the third person. Huge increase in D/D per month, way over the price cap % (DD gone from £85 to £331) and no one able to discuss this. Back dated 'debit' that has just appeared and impossible to dispute because the system crashed after spending 4 hours either on hold or speaking to someone who just repeated lines from a script. Can't submit new readings before the 1st deadline, but can today! Funny it is all working again.... Extremely stressful experience, I feel for everyone else also going through this with this provider.
