Expensive Tyre Supplier

I returned a car on Monday, and was later contacted as there was a thorn in the side wall of the tyre. I was then sent a quote from SuperTyres, their preferred supplier, for R1100. I contacted HiQ, Supaquick and TWT (all based near the airport), with all quoting under R1000 with the cheapest 18% lower than SuperTyres. However, Ashika and Customer Care at the Head Office are unable to do anything.<br> They are also unable to negotiate with the SuperTyres for a better rate.<br> Go figure - Europcar uses the most expensive suppliers in the market as their preferred suppliers and is also unable to negotiate with their suppliers!<br>
