Lenovo — regarding lenovo slow process

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I have given my phone to service center on 10th of december.
My phone is out of warranty and they told it will charge near by 1500 bucks.
That is fine but it's been more than 8 days and they said they don't have any idea that how longer it will take ; they are shortage of product so they are not able to deliver my phone. I need my phone asap. If you are paying and still you have to wait to get your things sorted. So there is no any benefit to go service center. And this is second time i am facing problem with lenevo service center. If it will go same then i prefer and recommend everyone not to use lenevo products.

I have submitted my phone in ambe electronics in c-30 sector-2 noida.
