Misleading migration done by Vodacom

On 03.11.2022 one of their consultant phone me to do the migration for increasing my monthly airtime from R245 to R410 and I'll only be charged R10.00 extra towards my monthly bill, to my surprise the bill is now R505. I feel that she manipulated me.

When I phone vodacom helpdesk I was taken from pillar to post dice yesterday without getting someone to assist with the migration reversal. Today I've been phoning from 09:30 and only got through at 13:00 due to high volumes. I sent 2 emails yesterday and today and no one responded

The consultant assisted with the reversal but he said it'll only be effective from 01.01.2023 and I won't be able to pay the whole bill of R852.99 whereas my normal bill is R687.00. Please assist with the intervention to try and resolve this matter.

I've been their loyal customer from 2009 having 3 contracts with them (R99.00 - 1 gig data plus pocket router, R245.00 - Huawei NOVA Y60 & R249 - 70 Gig Data) and I feel that this is unfair.
