Very bad experience with vodacom

We have been with vodacom for over 18 years. We upgrated in December 2023 and i asked the guy st the store if the amount he gave me is all i have to pay, no arrear amounts or other amounts and he said no, just the amount he gave me. I received the account sayiyng we are in arrears and they blocked our phones. Ok phone sgain and made the payment, they unblocked the phones. Now t hey have suspended it again. Went to vodacom today and they said we are begind with 600 for the December account, but i paid even more everymonth from december and the amount to unblock the 1st time. So today they said i can only have the phones unblocked if i pay thst amount, so its 3rd time now. They said if i paid the end of the month tjey will unblock today within 5 hours, so now i make this arrangement to pay this money again. Its hss been 8 hours and nothing. I phoned the customer care agsin and now they say that arrangemrnt is not in tje notes and they can only unblock when i pay. How do they communicate if three different places all say diffetent things? How many times and how much money do i have to pay vodacom just to get the phones working???????
