DISGUSTING BAD SERVICE

Today round about 18:00 a petrol attendant by the name of Mdluli on the M2 East high way .He insulted at us and refused to attend to us .We were at a petrol pump when he called the car behind us to service .When we and the guy on the other pump questioned this he said he will not help us , obviously we were upset about this we asked what kind of service is this he started throwing insults telling us that he attandends to better cars than ours .kanti does Shell's treatment to their customer depends on what car the customer drives.I then went inside the store to call the manager Mpho , he triad to calm the situation but no Mdlulu was up there .Even left me and the manager and he went to back to my husband now with his taxi driver friends trying to gang up against my husband. IS THIS THE TYPE OF SERVICE SHELL GIVES ITS CUSTOMERS
