Clearly, these calls are unsolicited and relentless, often following a brochure request that never arrives. Most victims report daily or multiple‑daily rings from the same Leicester number, with the company identified as Fischer Future Heat. The pattern fits aggressive telemarketing rather than a legitimate service appointment, and many users have resorted to blocking or reporting the number to Ofcom. If you receive similar calls, do not engage, request written confirmation of any offer, and add the number to your phone’s block list. Consider filing a complaint with the communications regulator and keep a record of call times for evidence.
