Hate vodacom ... HORRIBLE SERVICE

I’m beyond furious. I wrote my review Mid March .. vodacom did nothing. I phoned them again paid the account although I shouldn’t because it is the fault of vodacom that I was billed for a line they should have her cancelled. Firstly I was told that they see the 1000.00 I paid but the system doesn’t pick it up so it kicks out 2334.04. My sms on ph confirms outstanding 1334,04 ... I paid the 1250.00 (of which R400 should have been refunded because of the line that still opened dnd I asked it to be cancelled.) after 3 days paying vodacom I get sms about 1534.00 overdue.. seriously where does this come??? I decided to wait for my statement...and oh my goodness vodacom now tells me I owe the 1985.00 According to my statement I’m still billed for my other line????
