Pep unable to assist with policy underwritten by Hollard

Hi Hellopeter my name is Yvonne Sefako I am writing to you I need your help.I have a policy with Hollard under Pep Stores for more than 10 years. Last week I went to 2 different stores but I wasn't helped until today.They gave me an email to read and was provided with numbers to contact Hollard as they've changed all policy numbers we customers must call to get a new reference number to make payment. Until today their cellphone is ringing and no one is picking it up.I went to store again they can't help they say I must keep on trying, I did that but still nothing happened. I'm afraid should anything happen will I not be assisted.I took it on behalf of my father who is old born 1945 his name is( Obed Nkabinde).My policy number is *** ( My contacts is ***.Can you please help me .
