Billing and accounts are delayed????????

Good day.

i have been a customer of vodacom since 1994/5 and havent thought once about moving to another network even when you my number was disconnected from your system for no apparent reason. My account has always been up to date and now after so many years because of a glitch on your system i got a call to say that my account hasent been paid and yes it was paid via debit order. I called your ********** number last week twice?(Spoke to lungelo at 15:46 on the 5/10/2017) and was told my account is up to date. Checked yesterday to make sure and again i get a message stating my account is in for collection??? Called ********** again at 10:41am (forgot to take the persons name but i think it was noleen) she told me it would take 5hours for my account to reflect that it has been updated to paid. Went last night to do the upgrade at 7pm. Salesman tells me my account is still not paid. I checked my email lastnight after 8pm and got my invoice from vodacom stating my account has been paid? Called now again at 09:18 spoke to ayanda and she tells me the account has been updated and hangs up on me? Vodacom.....what is happening to your service? Do i now have to go to another network? CAN SOME ONE IN CHARGE THERE PLEASE SORT THIS OUT ASAP.
