Welcome to the community.
PP set this open forum up and you are not contacting PP directly.
See this link from the FaQ's
Remember your welcome pack, DD's are split 60% of annual projected usage from your quotation from Oct to March remaining 40% for the warmer months. PP does not offer 12 equal payments.
Revert back as needed including how to contact PP direct noted in many posts.
All the best
