FNB Connect Robbing Customers

I am absolutely flabbergasted at how FNB Connect robs customers. I have cancelled my contract on the 28th Jan and was told that it is a 30 day cancellation. The 30th Day falls on 26th February 2019. As a result the SIM will not be used for March at all. FNB Connect has already debited me on 27th January for the minutes that were allocated to the SIM in February.

Please can someone knowledgeable advise why am I being debited once again at the end of February when the last day for the SIM will be 26th Feb 2019. There is no need for you guys to debit me at the end of Feb as you will not be allocating me minutes and data for March.

I am tired of talking to you call center as they are useless and make no sense when they talk. I have also sent a previous email and till date no one has contacted me.
