Extremely disappointed

Extremely disappointed Ordered a printer cartridge online on 21 April 2020; Was supposed to be delivered in 5 - 7 working days. Since beginning of May I have been emailing customer support and received 2 calls back indicating the cartridge will be delivered within 2 days which obviously did not happen; then received a call again yesterday indicating that the delivery will go out today; I phoned a lady who gave me her direct no. to follow up seeing that it has still not arrived, just to be phoned back just now with NO delivery duo NO stock. I should now either go into a Makro store to be refunded or wait up to 7 days for a refund - AND I am still without the much needed printer cartridge :(
