The worst service you could ever receive from a company

I have been ****med i was advised i would need to pay 483 on the 28th of Jan of which 3 days later they wanted to deduct 448, when I call they told me that i shouldve paid 900 and something, I asked them to come collect their router, they refused to reimburse me as I have only used this for a week since I got it. I spoke to NMS on twitter who advised that one of the consultants will call me regarding cancellation and collection of the router, and that was on the 13th of Feb, they only collected on the 5th of March. Now they're saying I owe R3006 for the router lol that they collected and R507 debit order as to what am i paying for exactly if i only used this for 1 week?
