Poor customer service from Engen Penford Convenience Centre

I visited Engen Garage at Penford Convenience Centre today and filled up my car. Shortly afterwards, a friend of mine also filled up and received a promotional gift. When I voiced my disappointment at the inconsistency in customer service, I was met with hostility from the Penford Convenience Centre social media admin. Instead of offering a heartfelt apology and addressing my complaint, they chose to blame me for not asking for the promotional gift (which I had no knowledge of). ************** against customers is unacceptable. Either offer all customers promotional gifts or don't bother. I wouldn't recommend this establishment and would certainly not be supporting them in the future.
