WHY CANT YOU CREATE ME A INVOICE

WHY IS IT SO HARD FOR YOU GUYS TO CREATE ME A INVOICE? I reached out to the webafrica customer service on the 10th of July to ask why a invoice wasn't created for the payment I made on the 1st of July. I spoke to a Kristen that told me I need to wait 10 days after the date of the transaction (which isn't true I've been able to download my invoice a day or 2 after payment) I then reached out again on Monday the 1st agent Alicia told me they would request their finance department to create one. Set no time frame as to when to expect it. I then reached out again and spoke to Zanele who told me it takes 24 hours for the invoice to be created. Teausday I spoke to Yolanda who then told me it takes between 24-48 hours (Yolanda was literally one of the worst agents I've ever spoken to. 0 apology for the incorrect expectation being set no empathy was not attentive at all) as a customer service trainer myself you guys should really get her some training. Yesterday I spoke to alridge who again told me 24 hours and here I am with still no invoice. I want this sorted out as I need the invoice for work and every agent I speak to sets a false expectation for me.i already have to wait 2 to 3 hours for a gent to respond,it's not fair that I'm then met with ******* excuses and lies. Yolanda refused for me to speak to a manager,as such I would like communication from someone higher then a manager to rectify this for me ASAP
