The complaints, submitted in 2012, alleged potential abuses of dominant market position by Vodafone Albania, with specific concerns related to a suspected margin squeeze (as per AMC's complaint) and accusations of discrimination against competitors through an on-net vs off-net strategy, identified as exclusionary behavior (as per Plus's complaint). This paper provides an in-depth analysis of the regulatory actions and implications stemming from these complaints, shedding light on the complex dynamics within the Albanian telecommunications market. He backdrop of these complaints involves a press release from the regulatory authority at the close of 2012, signaling a pivotal moment in the industry. The filing of separate complaints by AMC and Plus against Vodafone Albania underscores the heightened competition and potential anticompetitive practices within the telecommunications sector. Notably, Eagle Mobile stands apart as the only operator abstaining from involvement in these regulatory proceedings. This research delves into the nuances of the complaints, dissecting the alleged margin squeeze and discriminatory practices to understand their potential impact on market dynamics. The margin squeeze, a concern raised by AMC, suggests a potential anti-competitive strategy that may limit fair competition and hinder market access for rivals. On the other hand, Plus's complaint regarding on-net vs. off-net discrimination points to exclusionary tactics that may stifle competition and impede a level playing field. The study also explores the role of regulatory bodies in addressing these complaints and fostering fair competition within the telecommunications sector. By scrutinizing the regulatory response to the complaints, the research aims to contribute valuable insights into the effectiveness of regulatory frameworks in curbing anticompetitive practices and ensuring a vibrant and competitive market landscape. In conclusion, this paper offers a comprehensive examination of the 2012 complaints filed against Vodafone Albania by AMC and Plus. By analyzing the regulatory landscape, the alleged abuses of dominant market position, and the subsequent responses, the research contributes to a deeper understanding of the complexities within the Albanian telecommunications sector and the regulatory mechanisms aimed at ensuring fair competition.
