Lenovo Warranty - Poor Business Practice

Warranty - Shocking business practice from Lenovo. The original 1-year warranty of my new Lenovo laptop ran from date of purchase in Oct-20 and expired in Oct-21. Prior to Oct-21 I inquired about extending the warranty for a further 3-years. After being sent from pillar to post by Lenovo (international), Partserve (service agent) and Tarsus Industries (RSA importer/distributor), I was referred back to my point of purchase - ComXpert International (online). I was quoted for a 3-year warranty and paid. After following up about the warranty for a seamless roll-over, the warranty was issued later. Much to my surprise I was shocked to learn that the 3-year warranty that I had paid for, had been backdated to my original purchase date, leaving me with only 2 years of the 3-year upgraded warranty that I paid for. I was informed by ComXpert that this was standard practice by Lenovo (or whoever has the authority to represent Lenovo). I find this misleading, ********* and dishonest.
