Never again

I last used RAIN in 202 and that was due to bad network - the first time I called in was to query the network and an agent told me that they have reset my network to pull signal from the nearest tower and I was like okay. Then there after the issues persisted . I then called to cancel my subscription and the agent I spoke to said that she will cancel and that was that. Never used RAIN again. Today I’m being called by attorneys saying that I owe an amount of R900 ?!! How when my last debit was R300 and just days later I cancelled my subscription!!! I’m not going to pay this R900. The failure was on the agents side to cancel as instructed by me! Not my fault!
