Poor service

Am extremely dissatisfied, frustrated and disappointed in Vodacom. I was owing them R770 then my line was cut off, managed to get R530 paid on the 18/08/2021sent my POP to *** still my line was unlocked. Instead the amount accumulated to R499. 74. I paid R500 yesterday in the morning, again sent my POP, been calling them the whole day upto this moment buy till now my line is still locked. The whole two weeks of non productivity because I need this cell phone to get to my customers. Your service is very poor.
