EXPO MARKETING SERVICES Complaints

I was offered Dhs 249 worth car service bundle offer thru Dynatrade Auto services who identified that he is calling from Dynatrade. On 29th I took my car for service at Dynatrade and was informed that it was lube services discount of Dhs 99 I can get and that I need to pay Dhs 150 for 5000 kms service or Dhs 250 for 10000 kmsm service. When I argued with Dynatrade about the offer I was told over the phone, they said they dont know what all EXPO Marketing has offered but these are their charges - take it or leave it. Also there was 2 car washes free which I can only claim if there is a repair work done at Dynatrade. None of these were informed to me by EXPO marketing. Real cheating. About to approach UAE consumer court online.
