Iberdrola contract renewal

Panic over, Whats the problem you may be asking. Well it all stems from an article and subsequent letters in one of the english language free "newspapers". We were informed, not reliably it seems, that change was afoot with our electricity suppliers. Those of us who did not hot foot it off to a far flung Iberdrola office and renew there contracts would pay dearly, no literally, hard cash up to 20% more than we need to, well that was the story. Fearing a price hike they could not afford many brit immigrants have in the last few weeks sought out the office in Pilar de Horadada and signed on the dotted line.(but what for we ask) We took the easier route and rang the company, no need to do anything we were told, you are on a free contract.
