Halfords cowdray avenue colchesterI had my dashcam and satnav fitted with them then i noticed my car started to have unnecessary alarms. Ive come to have it checked with them and they said just observe and monitor. I also told them its supposed to have a night parking surveillance but the dashcam said incorrect wire fitted. Next month i came back because of the same problem they said their technician resigned and they dont have available tech to see it. I came back the other month with the same problem and they said they’ll check the battery of the car which they said theres no problem. They said it might be the electricals (they’re the only ones who touched it). They asked me to book a car tech assessment and then i did. They booked me the next month due to tech’s going on a holiday and its the only availability i have as well. the lady told me I’ll be the first one to be seen and when i went there today at 8am as what is agreed, they said i was mistakenly booked. I cancelled all my appointments just to accommodate that day and they just wasted my time. I suggest not to let your car accessories fitted in HALFORDS! Waste of time and money!
