Forced warranty...no service

We bought a car through wesbank and as soon as one do you need to take an extended warranty they do not give you a choice... the warranty is through motorite whe had an warranty with them before no cause previous car already had warranty with purchase....no problems....but this time we bought the car from private seller out of a trust it took a while for sale to complete but last week we got a letter 2 weeks after car was bought that to keep warranty legal the car had to be serviced at an approved dealer from motorite that was not told to us and by the time we got mail the time to service was almost lapsed and the nearest approved dealer is over 200km away from us!! And since we can't just drive there it had to be planned...my husband tried the phone the number on the letter they send us to ask for extension or for some one to explain why this was not told to us before hand he could not get through the number given did not work!! But we were forced to take this with our purchase we are really disappointed with motorite!!!!
