@rnormans84 Sorry to hear about your problem which you described very clearly. SP are obviously struggling to cope with this situation if they have even closed the PAYG emergency number. Things change from day to day and we all hope that some order and organisation will return soon. Meantime if there is a danger of being cut off I would be prepared to borrow money to ensure continuation. I know this is not satisfactory but it may be your only way of handling the situation for the time being.
In this forum we are customers giving advice and we have no contact with SP management so we can only make suggestions.
We are in the same boat. We're on a prepayment meter and managed to top up our gas 2 days ago on the emergency phone line, but it hasn't gone onto our meter and now the line is closed, and we're about to run out today. We also need to top our electricity up, also about to run out today. My partner is 32 weeks pregnant with asthma and we're isolating. No reply on twitter or email, but need emergency help so we don't get cut off!
