I have been getting my bills but about 3 months ago i didnt get my mobile bill, went round to my folks and there was my bill and an overdue notice...even though i have never lived at my parents address?

my initials are EJ and mums are JE and we both have same surname and both live at #30 on our streets (and both with T) so i thought ah theyve stuffed up...some sort of automatic letter sending system that pre fills details or something??

and i rung and the lady was so rude and was like you must have changed ur address to your parents address,....i was like noooo why the heck would i do that?? no sorry or anything she made it out like i was trying to get out of paying my bill and told me i wouldnt get an extension on paying it so i hung up and rung back and got someone alot more understanding, but still no explanation HOW my bills got sent to the wrong address??

so wierd its not like it was my previous address or anything!!
