EE managing the situation
I had 3 of the first wave, one did get hot on its first charge. Took them all back to the shop, got one £20 voucher as the other 2 "weren't on the system"..... Didn't spend the voucher, twas all junk on offer really. A month later I get a marketing-head letter asking about the other 2 "Our records indicate...blah"
Given the small print says I get charged if they don't return to them after 18 months, I wonder which set of records will EE use....
