Sirago lack of service

I claim every month for a Libre Freestyle Sensor which my Gap Cover at Sirago pays regularly. On 26/10/21 my claim (claim CL61202) was rejected. Since then I have sent numerous emails, phoned just as many times, sent w/apps and is still waiting for the calls from an assessor that the lady at Claims promised will be within 3 minutes. So zero response/answer on my question as to why this claim was rejected (the reason being given is that I have reached my limits for claims), yet Nov and Dec's claims were paid out? I got an email address from another complaint to which Sirago rep**** on Hello Peter (***) and not even this mail was rep**** to. When I asked the consultant at Claims if they have received all my emails, she confirmed that they did. I am so frustrated with this whole business, can Sirago please man-up and sort this out??
