Billing query

I delayed this review for so long as I have never experience such terrible customer service from Vodacom since I started with them in 2017. I took out a tv contract with the black friday deals(yes that's how long ago), I queried the billing amount as it differs from the adverti*****t. 4th December i chat to "Ruben" via FB messenger and he said will escalate. No response after many follow ups, then 13th Dec i received a message "our team will be in contact". I didn't wait for someone to contact me and tried another way by calling on the 14 Dec, what a mission as I was being referred to "activations", "sales & upgrades" I can't even remember all the departments. Eventually I spoke to someone(by this time I was frustrated and didn't bother to take names)and she advised to send email to ***. 15th Dec i sent email, got ticket number 55825, no response 17th Dec i chat to agent via the Vodacom app, he escalated my query with ref number *** still no response from Vodacom. 24th Dec i chat to another agent via the app, the query was escalated to like minds and they sent sms, i gave her my contact number as the contract in question is not my contact number. Today, 30th Dec i called "sales & upgrades" spoke to Queen, who advise the has been escalated(i know this from previous contact but how long does it take to be resolved?)I asked her to check if my contact number was added, no she don't see the number and added whilst i was on the phone with her..so now it's waiting again for another 48hrs.
