Disappointing Service levels from Dischem

I placed an order online with Dischem for 6 items on the 6th of January 2021. My credit card was debited immediately and I was informed that the order would be delivered between 3-6 days for an additional cost of R 60. I accepted their terms and conditions and waited patiently for my order to arrive. I received an SMS on the 6th-day being the 12th of January that the order was in process. When I didn't receive my order, I then called the Atrium store at Overport city 3 times at 12 noon, on the 13th of January and asked to speak to the manager on my 3rd try. I was then put through to Kameel, who promised to check my order and revert within 10 minutes. More than an hour and a half has passed, and I am still waiting. Needless to say, I am highly infuriated as this is an unacceptable practice.
