Extended warranty

Hi there.<br> <br> We bought a 3 year extended warranty for a Lenovo Thinkpad10 but now a 2 years warranty has been app**** instead of 3 years that we paid for. We then asked them to correct it and that was 2 years ago. I'm disgusted with the service received. They going back and forth with Pinnacle Africa. I then supp**** them with the correct detail on 4 September 2015. They then corrected the start date but still on 2 years warranty so they need to correct it to 3 years warranty. <br> <br> I had a problem with the first thinkpad tablet 10 we bought cause Pinnacle Africa took 5 weeks just to find out oh they don't have the 128GB yet so we bought it somewhere else. Now we have this warranty issue. Can you just correct this ASAP. I want a date when this will be corrected or a signed letter when it expires (3 years from purchased date). The serial of the tablet is MP06ZV6Z. All I want ius to show us the 3 years warranty and close the matter here. I feel this is unacceptable and very bad service from Lenovo. I will therefore never suggest or buy any lenovo product again. This is now the 2nd brand that I will never support.
