Poor customer service at Shell SA customer service and Shell v+rewards card.

I fil up on the 22 April 2020 on where I also bought 2 500ml oil. To my discovery I received the ballance on my v- card to drop from R 122.25 to R38 on the 01 May 2020. Upon calling the numer for the v-card I experienced that my call ended as I reached no. 1 on two occasions. Taking in account that I was on the line 34 minutes and then 31 minutes before the call was ended by them with just a "goodbye ". I have tried to get something on the website for the v- card but the site does not cater for complaints or enquories, not even email. I decided to call Shell customer service but even there the lady was not helpful as she keep on refering me to the number that does not help. Even when I told her of the problem if you call she still inform that they do not handle. I post her a question that this is a product of Shell and carries the Shell name why not be able to assist as customer services but just not listing to my problem and just say nothing. On this call I spend almost 20 min with no tesolvement or even a appology from the lady. I also posted the question on the matter of client services as I used only Shell fuel and products on all my cars for almost 17 years that it must carry some form of credit as a loyal supporting customer in which she could not reply. Is this the kind of loyalty Shell is giving towards their clients? As person my moto is service delivery makes or brake a product. I inform the lady at customer service that I will no longer use any Shell product or service and that their loss will be R 2500 of fuel every month. Maybe this is not much loss for a big company but hope that this ends up with management that care about such a loss.
