Impossible to Obtain Invoice from MTN

Every 27th to 29th of every month the email with the account Tax invoice will arrive.<br> This month it did not. When you log onto their electronic billing website it states that some unknown error occurred.<br> So I contacted their 808 call line and I have been promised that the invoice will be emailed 4 times.<br> Only once did an email actually arrive. Unfortunately for the incorrect month.<br> The one person will tell you they are busy with software upgrades and she does not know how long it will take.<br> The next person will log a call and tell you it will take 3 to 8 working days to be resolved.<br> The next person will inform you it should take 24 to 48 hours.<br> But amazingly enough they debited my bank account! How is that possible if a Tax invoice does not exist?<br> <br> I tried to explain how critical it is for me to obtain the invoice on time as I need to claim the money back from the company I work for!<br> That does not help.<br> They are unable to assist and not helpful at all!!!
