Terrible service

On the 25th of October i requested my rain sim /membership be canceled the agent that I spoke to said that my sim will be canceled, their courier service will be in contact with me and they will come and pick up my router as well as i will get a refund of the data that I haven't used seeing that I only had the sim card active for a few weeks. On the 1st of December a payment from my account went out for the monthly subscription I had to continuously call their support and each agent gave me a different story... My sim only got canceled in the second week in December and they tell me that I don't qualify for a refund. This is absolutely ridiculous it's a fault on their part but why am i the that has to consistently call to get any feedback also whenever you log a ticket they never call you back. How long does it take to do simple things. Also the moment you don't pay their monthly fee they cut your subscription but when it's your turn to get money from them you must wait 16 business days this is absolutely nonsense its almost 2 months and nothing yet has been sorted out its not right at all
