Harrible customer service from PEP store China mall Durban CBD

The worst customer service from PEP store in Durban CBD China Mall, from the store Manager Sihle to the Cashier who has very bad attitude Lihle. The fact I came to the store twice waisted my petrol and no remorse at all was shown to the customer, I called for information and totally different information over the phone and totally different information when you get there. The cashier was so angry she threw the help line number to for no reason at all. I anded up not getting any help which I have to come back again all the way from PMB to get my parcel. This is my second time now that I have to come back without any help, cashier Lihle has very bad attitude. Can I please get help.
