Bridgestone South Africa
Found a replacement tyre

I wrote off a tyre (Firestone TZ700, 185/60 R15, for an Opel Meriva). When I asked at SupaQuik for a replacement under the Firestone All Roads Hazard warranty, it turned out that there was no stock of this size available in South Africa. SupaQuik put me in touch wtih Bridgestone who managed to track down a tyre in another province, shipped it to my nearest branch, and fitted it at no charge. Impressive.
