Our company has been a Regus/IWG customer for well over 10 years and, until this issue, we'd always had a positive experience. Unfortunately, what should have been a straightforward billing query has turned into one of the most frustrating customer service experiences I've encountered. Following the expiry of our office agreement, we queried an apparent increase in our final invoices. Over the next four months we received multiple and often contradictory explanations from different members of staff, incorrect invoices, numerous credit notes and repeated assurances that the matter was being investigated. Only after months of correspondence did IWG finally explain that the billing issues had arisen due to an internal system error following a termination rollback, which required corrective adjustments to our account. Despite this, late payment charges continued to be added to the account, and before our complaint had even been concluded the matter was referred to Legal Collections with threats of debt recovery and court proceedings. To make matters worse, our £8,106 retainer was applied against the account whilst the dispute remained unresolved, and refurbishment charges were deducted without providing a clear itemised breakdown or supporting evidence. Throughout the process we repeatedly made it clear that we were not refusing to pay sums properly due, we were simply asking for an accurate account and an explanation of the charges. Instead, we were left chasing different departments for months with no one taking ownership. The most disappointing part is that I had intended to continue our relationship with IWG by taking either a coworking membership or a virtual office at Berkeley Square. Sadly, the handling of this dispute has completely undermined my confidence in the business. I sincerely hope a senior manager reviews this matter and recognises that this is not simply a billing dispute, it is a customer service failure.

Everyone at the reception is fantastic! Big thank you to Alexandra, Katherine, Abhika and Cedric. This is my 3rd year at IWG Regus Berkeley Square. Any query/ requirement I have had, has always been swiftly responded to and dealt with 100% to my satisfaction. The team at reception are very helpful and professional. Always addressing all that arrive with a smile, taking time to understand questions/ requirements that come from both their tenants and their tenants guests that visit the premises. They provide a first-class service that is extremely hard to match by their competitors, which is why IWG Regus Berkeley Square have an excellent reputation and why I continuously promote the company to both friends and businesses. This is also why I continue to renew my agreement with your company. Thank you Dimitris Demetriou Rely Recruitment
