The protesters, who arrived as early as 6am, were attempting to unblock their SIM cards, which had been blocked due to NIN (National Identification Number) inconsistencies.
The demonstrators also blocked the Osogbo-Iwo road leading to the Oke-Fia area, causing traffic disruptions and gridlock.
The crowd included elderly people, pregnant women, civil servants, and other visibly frustrated customers, upset over the lack of service at the office.
Ismail Ademola, a resident affected by the blockage, noted that as of 8am, only customers from the previous week were being attended to, leaving those who arrived that day unattended.
Another customer, Ifeoluwa Dayo, expressed frustration after leaving her children at home early in the morning only to be told to return another day, especially given the high transportation costs.
Security operatives, including DSS officials, were called in to manage the escalating tensions and were stationed at the office.
At another MTN partner office in Fakunle, hundreds of customers were stranded due to a network glitch. Bashir Olaoye, a customer who had been visiting since the previous Friday, was told again on Monday that there was a network issue.
Despite having previously linked his NIN with his mobile number, his line was still blocked, adding to his frustration. He also complained that the online portal for linking NINs was not functioning properly.
A senior MTN staff member told Vanguard that the disruptive activities at the head office slowed down the process.
The official added that office connect centers across the state have been adequately supported to help customers link their NINs without needing to visit the head office in Osogbo.
