Can't register a claim with Telkom or Finrite

I lost my device about 2 weeks ago now I'm finishing week 3, I called and sent emails to register a claim but I can't get hold of telkom, I called and stayed on the line for a whole hour with no answer i emailed the insurer but my emails return, now I'm beginning to even think they'll even reject my claim cause they'll say I didn't claim in time.. I've never been so disappointed in telkom this much.. I think I'll cancel my contract and move to another provider Can anyone assist me with their correct contact details..
