GPS Location pin issues

I bought a hand blender from Masons Furniture online, 1st week of July and it got delivered to my place 3 days later. So last week when I wanted to use it I realized it had a factory fault. I called Masons to let them know and they advised me to take it to the Smeg service center in Linbro Logistics park in Molboro. I then called the service centre to confirm and was told I should come in anytime, they will help me. They gave me their address and the following day after the call, which was yesterday, I went to their premises. I put their address on my gps and drove over. When I got to the engine garage in linbro park, it said arrived. I then put in 1st avenue unit 1, then it took me to some deserted area that looked like a dumping area where there was a dead end , the place was scary and bushy… it kept taking me from one point to another around the bush until I decided to call the service centre and told them I’ve been getting lost for an hour and the gps keeps taking me to the wrong place. The lady I spoke to on the phone then took my number and sent me a location pin on WhatsApp, then I finally got the correct building. I am writing this review as I got disoriented yesterday, mentally n emotionally…. The whole time I got scared, alone in the bushes in a deserted area , thinking what if someone comes to hurt me… and right now thinking about it, I can see it wad just by God’s Grace that I got out of that place alive and safe. So please I would like to ask you to either fix your location pin on the maps or just by the Engen Junction, put road signs that shows where you are located, before someone gets hurt next time. That place is not safe at all.
