ITSure - no regard for customer service or satisfaction

Got a Lenovo tablet from ItSure through Momentum household insurance to replace a school tablet for my daughter and within the first week of delivery it gave problems and it wouldnt charge. Momentum was very helpful and immediately requested the guy from ItSure to repair or replace as it was still under warranty and replacement was urgent - my child needed it for school. ItSure collected the item from workplace, took it to PartServe for repairs. After having to follow up with ItSure myself, I was informed that the tablet was ready for collection (about 5 days later) but if I wanted them to deliver it to me it would take a further 2 days to get to me. I had to pick it up myself. After two weeks, the tablet has started giving me the same problem. Mind you, it's still under warranty yet ItSure (Mark) insists that I take it back to PartServe myself - as if I have a deal with PartServe and has ignored my please to process and sort my issue out for the past 2 days.

It really is exasperating!
