Charging Customers for Services Not Provided

Last night, a consultant contacted me to inform me that I have the option of either having my current router collected or being billed. I was taken aback by this and informed him that I would need to reevaluate my services, as I have been a loyal customer for five years and have consistently paid a premium of R1450-00 per month without complaints. I was not provided with any prior notification; the next morning, I received a courier notification informing me that the router would be collected. I had not canceled my service, and as it stands, I will continue to be charged for the service for 6 more weeks, but I am unable to use it in the absence of a router. Is it not reasonable to anticipate that your equipment will be collected at least a few days in advance, allowing me to make alternative arrangements? I have since received acknowledgement from customer support that my cancellation is accepted and will be billed till end of April!!
