FutureTech at this point is basically just a sales place. They'll sell you Apple products at exorbitant prices, as if they weren't overpriced to begin with.
Every time you ask them about a service or repair related question, they'll either ignore you, say it isn't possible due to lack of parts, OR ask you for 50,000 rs, and your damaged product and you take a new one from them.
I asked about a battery replacement on my 6S Plus and first the guy said due to IATA regulations, Pakistan isn't allowed to import lithium ion batteries, and then after that he said, we'll take your phone and 50k on top and give you a replacement phone. Mine was working perfectly except for the worn out battery so there was no way in hell I was giving them shit.
You can buy products from them, but don't expect good after sales support.
