Charged For 6 Months

Good day<br> <br> I had a Mweb account. In December I moved premises and had everything cancelled. I did a online cancellation on my Mweb account and assumed it went through because it showed me that it is going to be cancelled. This was done within the 60 day period. I didnt check my bank account for debits going out because I havnt been working and have no money in my account. Its 6 months later and I have a bill for R 1080.83 from ITCBA. My account history shows I havnt used any data from Mweb nor did I access my account online. The number that this account was linked to is inactive. After speaking to Mweb they say I have to pay because I didnt cancel my account (or never do it properly). So Im expected to pay for something I havnt used for 6 months because they say I didnt cancel and if I did I should of got confirmation. I didnt even know that I am going to get something. How is it that the customer just gets told \ oh we cant help you
