Vodacom agents out to ROB loyal customers!!!

For the last 2 months I have struggled to get proper assistance from Vodacom. As I have 2 active contracts listed on my name, an agent called me and offered to upgrade both my contracts at an affordable rate, but has failed to explain the payment terms in details. I have been battling to get context on these contracts from August 2020 to date, adding further worries and frustration on my contract where 500 additional minutes have been added to my phone, which I have not purchased. on 6 October, around 7pm, I spoke to 2 agents, who seemed reluctant to assist me and has caused me added frustration. In total, I have spoken to 11 agents for almost 3 months and none of them have committed to helping me with my ongoing issue. I have been with Vodacom for almost 12 years and this is the thanks I get for being LOYAL??? This issue needs to be sorted out the minute someone from VODACOM reads it and I refuse to talk to another AGENT!!!!!
