Bad service

I had three cell phone contracts with Auto page. Number *** had a problem with handset, it took 16 to replace handset with second hand handset. This happened in the second half of 2014. My other contract *** was stopped and my contract end at the 1st of July 2015. They invoice me till the 16th of July 2015. Notice of cancelation was done 3 months ago.<br> Phoned the service center and the operator dropped the phone in my ear when I did my enquiry. Also my tarifs have been adjusted without notifing me at all. Worst client service ever
