Payment by phone unsuccessful. Transferred from pillar to post without help to pay our final statement as we have switched supplier upon buying the property. Transferred back to payment line where the customer number was denied several times and disconnected. All three staff I spoke to were extremely unhelpful. Payment line sucks. Had to wing it with bank transfer as customer number for banking transfer reference is too many characters. Absolutely AWFUL service. Glad this is the only experience I had to undertake with the business. If I could give negative stars I would.
