Useless customer service. I sold my flat 1st July 2025, and I'm still receiving bills (today is 24th July 2025) They sent me a refund of £1.88, that was smooth enough, now the account is showing I owe them £1.88. When I asked why they said, "This is due to two refunds being processed for the same amount. The second refund was intended to be returned to us.".. I've just checked my bank account and I only ever received 1 refund, not 2. The next line in their email reads, "We kindly ask that you settle these amounts as soon as possible to avoid debt collection letters and potential late payment fees." Lovely and threatening tones when they've made a mistake... How hard is it to refund someone and close an account...
