Unhappy customer

I bought 2 Lenovo tablets on the 4th of August at the Westgate branch. Almost 2 weeks later one of the tablets stopped working and took it as I took insurance for both phones. A month later was called to say the insurance does not cover software problem. I refused to pay and they told me they will claim again from the insurance but they do not promise the will fix it. Today the 29th September I called the branch and an answer I would get from Zane is I don't I don't know. Bought both phones cash for kids school work and my daughter still doesn't have her tablet. Very shocked with the service.
