Uncapped Bull****

I am so fedup with Telkom. I ordered a wifi router and received it on the 7th April 2020. When applying for it, I asked specifically if there will be any interference as I will use it for y smart tv to stream. I was advised all will be fine. On the 21st April 2020, the red light on my modem went on. I called numerous times, finally given the answer I was NOT looking for. I was advised that I ran out of data, on my 10meg uncapped bundle!!!! How?? used it for a week only. I want to cancel this contract, I want nothing to do with Telkom. You can take your modem and contract as it is useless. I went online to cancel, and your system just hangs. I am asking you nicely, please cancel this contract NOW. I will only pay your pro rata, not May's full debit. I do not want this thing in my house anymore I had this thing less than 2 weeks, in terms of the agreement I can cancel within 20 days.
