Be careful when buying a TATA

We use 2 Super Aces LDVs for garden service. A radiator packed up and now Tata tells me it takes 3-5 weeks to get one in stock and no-one can even give me an estimate of cost. Tested 6 other makes for the availability of a radiator and ALL can supply to Langebaan within 1-2 days. I tried to contact their headoffice and manged to get a person who could not really help but try to go higher up and the don't even answer their phones. Obviously all Email adresses are kep a very close secret, So if you consider buying a Tata be prepared to wait for weeks should anything go wrong!!!
