option 3 no longer sold
this is the options on renewal http://www.productsandservices.bt.com/consumerProducts/displayTopic.do?topicId=27281
if you want to change then phone the options team 0800800030 and complain that you were sold the wrong packages - probably the 'extra' is the package equivalent
Obviously you did not check the packages on offer before renewing. If you need more cloud space or net protect then you could try upgrading to extra by phoning the options team who are uk based and usually very good. 0800800030. Up to you
there is no cancellation period for renewals as service already active
If you phoned up to renew, they should have told you that you were being switched to a different package. When I phoned to renew back in March, they were quite clear that it was a different package i was being switched to, with different options*.
If you weren't told, don't just accept it. Make a formal complaint that the operator mis-sold you a different package without telling you.
*That said, BT's system is now hopelessly confused as to whether I should have Netprotect Plus or not. If I log on to MyBT, it tries to sell me Netprotect Plus as a monthly add-on. If I click the link for more details, it tells me it's included in my package at no extra charge. In reality, NetprotectPlus still works for me.
