Poor Service!

I made a payment through my banking app on the 28th of May 2021 and I sent them the screenshot of the SMS as a proof of payment, I didn't pay for the delivery fee as I didn't want to wait forever for my order to be delivered. I sent that proof of payment together with the picture of the hair I wanted and said I'll come and pick up my order later that day at Roodepoort branch. When I got there they said I should send the proof of payment in the form of Pdf and I did exactly that immediately, I was then told that the payment needs to be confirmed first before I can be given the hair which they didn't specify on their Facebook page, but then I was promised that the payment will be confirmed the following day which was Saturday. I contacted them on Sat to ask about the payment confirmation and they said it's not yet confirmed but they will let me know as soon as it's confirmed. On Monday the 31st I contacted the branch but there was no response, I then phoned the branch manager and she took my details and said she will get back to me on WhatsApp which she didn't, I sent her a text on WhatsApp reminding her and she also said she will let me know as soon as the payment is confirmed. I asked her when will that probably be but she didn't answer me until today Tuesday the 1st of June 2021. I am so disappointed with their service.
