Lenovo — Lenovo M10fhd fhd plus tab

I need an active pen for my tab and when I contacted while buying device they said you can buy separately. Due to budget issues I only bought tab at that time .Now when Iam trying to buy active pen they are saying that there is no compatible active pen for my device and when I asked for solution they hung up on me rudeIy I didn't expect this from Lenovo support team I expected a solution for my problem. Iam deeply disappointed .How can I buy any other product from Lenovo again I really need active pen for my tab .It's only two months I bought this thing. I need an active pen please find me solution I will pay extra amount for pen.Iam expecting a solution from your side .Iam ready to replace my item and get another tab along with active pen by paying extra amount ...
And other issue is about customer care service how can they hung up on me rudeIy ... deeply disappointed with this behaviour .
I didn't get solution and upon that this rude behaviour.
