no network and no communication

I haven't had internet connection since the beginning of September. I lodged a complaint regarding the network issue and it could not be resolved so I opted to cancel my subscription on the rain app. I was advised that they would bill me for the month of Sep even though I have canceled and I would continue to being connected to the network until the cancelation date. my network issue was escalated to the network department and was promised a call back with regard to the network, till date- I am still waiting for the call. I was also told that I would receive communication with regards to the collection of the router , I am yet to receive such information. RAIN IS REALLY A **** AND TOO GOOD TO BE TRUE. COME AND COLLECT YOUR DEVICE BEFORE I OWE UNNECESARRY MONEY, and please do explain to me why I will have to pay for a service I did not receive
