Poor service

I got retrenched end of May, I informed Woolworths as I have an insurance on my account.i was sent a document to complete and return with other documents such as the retrechment letter,I'd copy,statements ,last payslip etc...

I did that on the 13 th of June,on the 17th I was asked to resend the documents as they can only see my id and not the other docs.i resent the docs. I followed up with emails and calls but was never assisted.apparently I cannot go through to the insurance department, someone internal must email them. To this day my query is still unresolved. I got an email Monday asking me to confirm my id or account number. I sent a nasty email back as I could not believe that a month later I'm being asked for info I sent. This meant to me that they have not done anything with my query. Woolies is such a reputable company with high standards and quality but the service from their insurance is disgusting to say the least . I am so disappointed and angry at this point.
