Upgrade results in additional fees for value added services I did not ask for

I upgrade to a 24 month contract for R419 per month, with helpful customer service. Then I get a call from the department confirming my upgrade that tells me I will be paying R538 per month. Then Morne and Zandile (the person that upgraded me) transfer me to accounts and I am informed by a robot voice that I am blocked from the call centre due to high call volume. I have x2 value added services that have been added to my invoice that I need removed.

I haven't called many times and I am completely confused as to why I have been blocked. I feel ****med at the moment because I am struggling to get rid of roughly R115 in value added services that I did not ask for.
