LRP - BP's lack of support

It appears that a simple request for information about where to get LRP petrol in the Western Cape cannot be answered by a large corporation like BP Southern Africa. Tried their web site - no info. Looked up their contact page where there is a call centre number. Unfortunately, it was a Saturday and they don't work on Saturdays - fair enough. There is an email address where visitors to the site are invited to send complaints or queries. Sent email to the provided email address (***) on 18th December 2019. No response. Called the call centre number *** and spoke to a Rhona. After explaining my disappointment at not receiving a response to my email she advised that the email address is only answered by one person and that person had moved to another department! After explaining to her what information I was looking for, namely which service station in the Westen Cape sell LRP grade petrol, she put me on hold in order to speak to her supervisor. When she came back she said that the marketing would get back to me. I gave her my email address and mobile number. I also explained that the reason I want to know is so that I can advise member of two classic car clubs that I belong to. That was this morning. Guess what................no email and no call from them yet. Surely such information should be at someone's fingertips in a large organisation like BP?
