Payment made on the 23 May 2020 to settle the devices

i have found no joy in vodacom dealing with my query since May... i payed to settle the devices and continue with my monthly package i called on the 25 May where a lady confirmed she can see my payment and she is going to close the devices.. i have been calling every week where agents don't see the notes of the people i have been speaking to, on 2 occasion i have been promised phone calls back, the first query back office sent me a reply and stated my proof of payments have not been attached,..... i have sent the proof of payment and the cancellation to vodacom now another query where i have to wait again... this has been dragging and its now the 3rd month where i have to wait... call ... be told you need to lay a complaint per department your service sucks
