Acer India — installing a ssd

Address:

208002

I want to install a ssd in my laptop from service center but the service center guy said that acer had to approve the ssd then only they will install it so i contacted but acer is not giving me response instead it is torturing me mentally. I am so tensed that i cannot install ssd in my own laptop. They told me that i am allowed to install a ssd only if i purchased from acer which is exactly what i did but they told me that acer dont sell ssd u have to get it from outside and service center guys will change it on chargeable basis so i did the same but now the company is stalling me and not letting me install the ssd in my own laptop i need them to install so that my warranty is not void please help me i m very much anxious since 21 days my money in ssd is also getting waste
