Been in real estate for years and we needed reliable energy backup for our office, so a colleague referred us to Schlumberger NG. The technical team that came to assess our setup was proper knowledgeable sha, they didn't just sell us something we didn't need like some companies do. What impressed me most was how they explained the whole system before installation and actually followed up two weeks later to make sure everything was running smooth. For what they charge, the quality of their service and how responsive they are to issues is worth every naira honestly.
