Absolute Inconvenience and Disadvantaged by Tremendously Poor Service Delivery

Poorest service delivered. Sent the incorrect purchased item. Returning it was dragged to be the most lengthy process ever. Purchase and paid for a product on the 5th of March. Today still have not received the correct product. When you call the center, calls are rerouted to other customers. Ive expressed over 10 times that the item I've purchased is an important component I need to perform work tasks. No sense of urgency. I expressed that the component I've purchased is available on other international online stores but shipping would be over a month. No sense of urgency. If I knew it would take an entire month for their five to ten working day delivery policy, it might as well have been better of to purchase the item outside the country. I offered to deliver the incorrect item to them myself and pick up the correct item for a refund of the R79 delivery charge, this making things easier for them and accelerated for me hence the inconvenience already endured. The offer was declined and was told that a courier will be arranged. 48 hours later from that communication, a courier arrived and collected the incorrect item. On an email sent by one of the consultants, instructions detailed the following, to arrange an additional box to place the item in (which is already in a box), to print 4x waybill documents for the courier and sign them upon providing them to the courier. I have been tremendously inconvenienced and disadvantaged by this company.
