Vodacom and hallmark disgusting treatment

2020 I received a call selling me a vodacom wifi router contract which I took,and while on the call I cleared made myself clear to the consultant that I do not wabt to pay more than R250 because that is my budget she agreed and said not worry this will be like that you won't pay more than R250,a month after receiving the contract I get a call telling me that the contract is an open plan but they're going to try fix it, I waited I called again I was told I have to wait for the contract to be 3 months old before they can log a request to change the plan to top up, it's safe to say I waited from August last year til today nothing is happening, I then requested a cancelation since they're unable to assist me with putting me on the right plan,but instead vodacom went and debited R903 in my account saying I went over board to my surprise because at that time I was sure that my contract would be moved to top up because it had been 8 months requesting them to do right my me,which they failed instead they sending me form Pillar to post telling me to call hallmark saying they're the ones who I took the contract with, I keep asking them who is HALLMARK,on my credit records I have a vodacom not hallmark who their 3rd party is is not my business am a customer who was not treated right and it's their job to contact their 3rd company to assist but even today nothing has happened, I then called hallmark myself wow they alps saying they waiting for vodacom whole vodacom days they waiting for hallmark, am extremely disappointed with vodacom all I want is to close this contract.i even remember the consultant who told me about this contract her name is Mandy but now can't seem to fine her,and amazingly RAm couriers was sent to come pick up the router form my house but now both vodacom and hallmark say they can't find the router, I don't know what is so hard to call RAm and find out what happened, am stuck here not knowing who to turn to and it was not even my fault. I have so many ref numbers but nothing seems to help because I qoute them and still it's like am joking because they juts numbers to them, I even contacted vodacom on their social media platforms and tehy still did not take me serious, VODACOM DOES NOT TREAT THEY CUSTOMERS FAIRLY, THINK TWICE BEFORE TAKING A CONTRACT WITH THEM.
