Gigaleads truly impressed me. From the initial contact to the final results, everything was well-organized and highly professional.What stood out most: they think along with you, act fast, and stick to their promises. No empty words, just leads that actually convert. My calendar is filling up with high-quality appointments. For entrepreneurs who want real growth without the noise, this is the team to work with. Great job Gigaleads!

I worked here for 3 months and my experience was (contrary to the reviews below) very nice, easy going. The management accommodated my personal circumstances and provided ease into adapting to the role, support was always available as well as humour and banter from colleagues. Perfect transition job from hospitality to office roles. Bonus points for progressing employees internally to higher roles accordingly.

How did managers help with a transfer of service for a customer who left review.Because at managements rule is to never disclose that they are calling from at management,they are only to represent and use their clients name. What’s even funnier is this customer was considered special from the rest. They were not only informed it was at management dealing with their service but they even knew the real names of the managers.Another common practice is staff and managers mostly use a dummy name not their real. But in this case even that info was provided to the customer. Must be a special customer that the normal practices were broken for them and they from millions of customers even took the time to write a review lol . Everyone laugh with me.

Both Adnan & Connor at AT Management were superb in their dealings with me over the transfer of a service when I was moving house. Nothing was too much trouble & their knowledge was very good. I’d have no hesitation in recommending these two individuals or AT Management
