Cell C shoddy service

Using this platform is the only way to get any proper response from Cell C. I am on a prepaid contract and use the Cell C web site to purchase data and airtime. There is a function on the website to request an invoice once the purchase is made. This however does not work. Because I get no invoice I then need to send an email requesting the invoices. I get an automated response that my query will be responded to in 24-48 hours. If you believe that we'll good luck to you. I requested my invoices on the 22nd September and guess what?, yes in true Cell C style. Still nothing has happened. Each time I speak to a consultant I get a totally different story. Nobody there actually seems to understand how their own systems work. All I am requesting is my invoices how frigging difficult can that be. I sent all the relevant info that was requested. How many times does a person need to call and email. We'll considering past history my last query only took 7 months to solve. So I really shouldn't be surprised that a simple thing like 3 invoices can't be resolved easily.
