Shocking service at Dischem Watercrest Mall

This rating is specifically for the Water crest Mall branch!! I would prefer to not even give the 1 rating if it were possible!! With my daughter & husband having tested positive to Covid I needed to to a rapid test as well. As advised my Dischems website I used their booking system to schedule an appointment at the water crest mall branch, which is about 40-45mins away from where I live. My schedule appointment was for 11am today. However upon arrival at the clinic I was met with a rude & condescending young women who laughed off my appointment, stating that the o line appointment system is actually not syncd to the store itself so it's 1st come 1st serve & she then proceeded to direct me to the back of the queue. When I ask why the booking system even existed if it was not used she sarcastically shrugged me off & told me to "just take a seat". I ask for a manager to be called as I wanted to understand why there would be the option of an online booking that doesn't work?? To this the assistant sarcastically laughed at me & proceeded to speak in her native language, which I do not understand, to the other patients in the queue, at which they all laughed!!! It's now been an hour that I am sitting in the queue & have not moved!!! I am sick. I am miserable & all I need is 1 rapid test to confirm or rule our covid... But nothing!! Further to this. The clinic queue is not even being monitored or watched. A man just joined in mid-way because his friend allowed him to!!! I had taken a relative to a govt hospital 2 weeks ago for testing & the process & staff were a whole world easier to deal with!! The service, lack of management & the attitude of staff at the branch is shocking!!! I will never ever visit this store again & would recommend the same to all I know!!! By the way.... I'm still waiting!!!
