It is hard work.
As well as the usual stuff, my DH had all sorts of subscriptions, some not easy to trace as all records were online. A couple which I only discovered after a few months were paid for via PayPal but I had already closed that account. It took a huge number of messages and calls to sort it all out. I kept his phone and email accounts open for several months to make sure nothing was missed.
On a lighter note, when the time came to sell his two ipads and two mobiles which were still fairly new, my grandson, then 18, came with me to the shop, Cex, which buys and sells such things. He said, “ We’ll go together, Granny. If you go on your own, they might try and rip you off. If I go alone, they’ll think I stole them.”
