Refusal to allow me to read contract, in PDF and sign and THEN send back by Budget

I was contacted by Thabang for a quote for a motor warranty. Whilst the deal sounds good, what is covered and what is not covered. We got to "major sensors" and he could not explain, if it is parking sensors or engine sensors. Then when we got to the part where he wants to process when payment must go off, i backed off because as a matter of principle I don't conclude contractual agreements without having something in writing. How difficult can it be to (1) send me the contract in PDF (2) I read through it, including the fine print (3) I sign and send it back. NOPE, Budget does not do business like that. I bought a motor service plan from VW, all online, via PDF, which i signed and sent back. In this age of online *****, it is easier to conclude a contract telephonically than in writing. That is worrying. Well you just lost a sale..
