Rain does not want to refund me my money

Im honestly disgusted by RAINs service. on the 15th i got billed double and when i called the Support time i was told that they made a mistake and they will refund me within 7-10 working days. Today i call the support team to make follow up on my refund as it has passed the 7 days. The agent Ken said unfortunatle the refund was not processed. Imagine having to wait for another 7-10 working days for my money that was debited without my contest. RAIN i am reallyh dissappointed in your service :(
