Billed for a SIM I did not request

I have not used Rain in years. Suddenly I see I have a months' worth of outstanding bills for a SIM that I never requested. How was this done without my consent or authorisation? Why has it not been deactivated after months of no payment? I see similar reports from other users both here on Hellopeter and elsewhere. It seems you have suffered some kind of security breach and are either unable or unwilling to respond. No luck on your WhatsApp number, no e-mail address, and I don't have time to wait hours on end for your call center only for the call to be dropped.

I have already forwarded this matter to ICASA in the hopes of a swift conclusion, but would like some recourse from Rain itself, as ICASA also tend to take some time to resolve an issue.

Do *not* contact me telephonically, you can provide me with an e-mail address for discourse - or request my number and have an actual person WhatsApp me (do *not* phone me, I will not answer).
