Tried calling me?

My claim has been finalized and the bank mandate forms sent in last year. When I phone the call center for an update on when payment will be made, I am told that they tried phoning me to confirm my banking details and if I am still alive, but their was no answer. I asked them on which day they phoned and they said on 4th and 5th Feb. I checked my phone logs on those days and there were no private number missed calls at all. I phoned back and was told that they will log for someone to call me again in the next 7 days and if I don't answer the phone, I will not be paid. Surely they should be phoning my bank to confirm details. I strongly suspect that this is a new tactic to not pay. Is there anyone else that is having this problem?<br>
