Hp — mouse stopped working sent for replace yet not get replaced item

Address:

Guna, Madhya Pradesh, 473001

I purchased a hp laptop on 23 july 2018. Along with i purchased a combo of bluetooth keyboard and mouse of same co. After some days mouse stopped working then i contacted your hp world center and sent it along with keyboard for replacing with new one, as it is in warranty period. But not yet received replaced items. Hope i will get replaced items soon, as i needed them very much for my work. Thankyou
