Very bad experience, will never recommend [redacted name] from Sri Choice (pvt) ltd. Though Sri Choice was $50 - $100 cheaper than others initially but proven too expensive now. Even if we ignore the unprofessional behavior of reaching 2 hours late, still the poor quality work and ZERO service. Battery is not working and permanent warning sign showing. some days later another issue popped up, alarm is beeping every minute with warning sign blinking. informed [redacted name] but replied couple of times to ask issue after that no action taken, neither call/msg replied nor problem resolved. Horrible experience with [redacted name] from Sri Choice (pvt) ltd.
