loyal customers discriminated against

I have purchased a TOM TOM Via Live a few years ago - Map updates have up to now cost me yearly over R1 K - I contacted Tom Tom via email , Facebook and twitter without any response yet on why I must pay this crazy amount when they sell new GPS for around R1.5K with lifetime free map updatesThis year they want R1119 for the SA Map update ???. Surely map updates should be free for all or at least be discounted to make it worth my wile to stay a Tom Tom customer. It is no use phoning there SA call centre as the number rings for a long period without being answered - see facebook for more complaints about that. One cannot find a SA e mail to contact TOM TOM so I mailed the international web site address This is their response <br> :Reference Number: ***<br> <br> Dear Mr ***xx<br> <br> Thank you for contacting us.
