Cellphone contract

I have app**** for a contract at the Cellucity store at N1 city. At first I thought the service was great as I was able to complete my application without going all the way into the store as it was sent via email. I completed the forms and sent this all back on the 10/06/2020. The consultant came back to me the stating it was approved but I needed to make a payment first which I was more then happy to do but then she tells me that I need a link and for some reason she could not send the link via email but she will consult with their IT as this payment needs to be made directly to Vodacom. The following day I have not received any email and I had to follow up by calling the store the consultant helping me with the application says she has still not had any feedback from their IT but she will get back to me. The next day I have had no feedback I called the store again to ask if I can pay in store rather and was told no it should be made via this link and was told again they will be in contact with me. I have had no one contact me since Friday when I called the store and I had to send another email to follow up! The poor customer service I am receiving is beyond me why is no one following up with your IT department or with Vodacom about the link I am waiting for. How is it so difficult to apply for a contract? Why should I as the customer follow up and no one gets back to me as promised?!
