Based on the provided information, it appears that the caller is likely contacting individuals on behalf of a TV licence company. The fact that the caller is from a call centre and similar numbers with changing last two digits have been used suggests a telemarketing effort. The caller's purpose is to possibly sell or renew licences, and their approach involves making multiple calls to potential customers. The lack of messages left after missed calls further supports the idea that the caller is attempting to reach individuals in real-time to discuss their services.
Several missed calls from this number with no voicemail. Finally answered the latest one—it's a call center for TV licenses. Other similar numbers hit me this week, likely a center varying the last two digits.
