Vodacom fiber and their consultants

I feel like vodacom Fibre suppliers are a ****, heres why, I have a two years fiber contract with them since 2024 April and everything was going fine untill I became financially unstable because of a suspension from my work place so could not afford to pay for two month however on the third month I called vodacom enquiring about my balance of the missed debit orders and I was told it now amounts to R3200 I then asked for some more time and I will settle the amount and we agreed, then two weeks down I get a call from a different consultant asking me how much am I willing to pay or should we continue with amount that I was paying monthly which is R1019 and I agreed to that amount with the hope that after settling my account will be activated, on the 24th I went to the nearest vodacom shop with the aim of settling and continue with contact but I was told I agreed to pay off R12300 of which the consultant I spoke to never made me aware that am now paying to settle the whole amount of a contract and should he had clearly stated that it is now R12000 that I am agreeing to I would have made means to pay it off to avoid. When trying to explain how the consultant mislead me to agreeing to such all I get is "SORRY FOR WHAT THE CONSULTANT DID BUT THERES NOTHING WE CAN DO" so I have to pay R12300 without the services, please can someone tell how is that fair.
