Frustrated and sad customer

I went to Makro to purchase my groceries using page just now and exceeded with R56 and my transaction was declined and upon removing one item the first transaction went through leaving me with a payment made for goods I didn't receive. My money was gone like that and I tried all avenues to get help from pay just now using their chart bort calling and sending emails but nothing was done. I didn't get help. I'm so frustrated and irritated with their services and regret having this app. I will definitely deactivate it as it is not beneficial at all but frustrating. Calling them is worse there is no answer. I guess they operaters are robots.
