Bad service and poor network

On the on the 2nd of February I signed up for a rain loop router normally you pay in advance before you use the router now due to the lack of customer service and network problems I decided to cancel the router on the 20th of April and on the 24th took back the router to the nearest store in soweto dlamini junction. Now on my first payment I use my wifes bank card because I did not have enough funds in my account. I opted for an EFT instead of a debit or a but for some reason rain decided to save my wifes person's banking details without her permission which i consider ***** because i also didn't give them permission to save mine because i choose eft and now today is the 25th of April they debiting from that person's bank account without their permission and after canceling no email was sent to confirm that the cancellation was successful. Its the 25th of April don't have the route with me, i cancelled it in time. And if they continue to debt someone bank account that did not give them permission i suggest she takes this Matter further to the ombudsman. I cancelled your poor network loop cancelled it from your side because you will not be getting a cent from me
