Experience with sse is beyond a joke. I have a bill that’s on a closed account which is over 3 years old. I had a payment plan set in place for 2 years then because my daughter was in hospital having a back operation one payment wasn’t made so they cancelled the payment plan without me knowing at all!! Until 2 weeks later had a red letter saying I owe over £1000 now! I called many many times and they would hang up after 45 minute holds to get told they would only accept DD doing forward to set one up. Yet paid by bank transfer for 2 years!! Spoke to them again after continuing to make payment via bank transfer that they will be sending it on to debt collector even though it’s being paid because it’s not via DD. So ot will be passed on even though I am paying each month! This company is the worst I have ever dealt with and should not getting away with operating this way! I have contacted citizens advice who said what they are doing is illegal yet continue to do it this way!! Human empathy doesn’t come natural to there’s people!
