My requirements for claiming-and feedback

Hi<br> <br> I have called the call centre and was asked for my bank statement showing that I have been paying. I sent the bank statement through because I needed to claim for my lost Ipad. However,nobody has called or e-mailed me back with regards to what documents I need to submit in order for them to start processing the claim. It has been 4 days now,not even an acknowledgement of the e-mail.<br> <br> How does one become an insurance company but does not want to provide feedback?
