c-surance is robbing us

All of us know that cell phones , like cars lose value with each day that passes, yet we have to pay the excess to the value of the phones original price which it was insured for but cannot get a newer phone to that same value even though it is in their terms & conditions, therefore they are in breach of contract because we are paying for up to 15% of the original value but getting the same phone we lost that is now worth a lot less. This is a Q&A from their frequently asked questions on their website but do not adhere to this, \Can replacement phones be different models?<br> Handsets will be replaced with equipment of similar specification
