UTTERLY POOR CUSTOMER SERVICE BUT MORE THAN HAPPY TO TAKE YOUR CASH!!!

Ordered a cartridge bundle from "Ink Star" online and paid for 4 (four) "compatible" cartridges for my Canon printer and when they eventually arrived (no printed invoice supp****), one of the cartridges was well past its expiry date and the others were not far off either. I needed to print immediately and had to install these cartridges. Ref: 7378; Order: INV27580 Another shipment arrived with the same order a day later but with a printed invoice this time and instead of keeping the extra set, I thought that I'd let them know via their WhatsApp number. The contact person on the invoice that came with this set was Felicia. The person that responded on WhatsApp was Lesleigh. She/they were all too happy to arrange the collection of the extra set. However, the expired cartridge has started leaking causing my printer to malfunction and when I contacted them via WhatsApp yesterday, enquiring about the warranty, and again today, the messages were read (double blue ticks) and ignored; however, I am yet to receive a response. My query related to the warranty on their "compatible" cartridges" and there is radio silence, probably hoping that I will just give up in trying to contact them. It also seems quite suspicious to have 3 websites for the same business; inkstation.co.za; printstation.co.za and inkstar.co.za. I ordered online from Ink Star and order was received from Ink Station. Account on Ink Star profile has the invoice but there is no account on Ink Station to view said invoice. This is not how you treat customers who have a valid query.
