Rain : 17 days waiting time for my Refund Shocking

I must say I am really disappointed at Rain and their processes as I had made a double payment in error for my services on the 20th May. I phoned Rain customer service to get assistance for a refund the very same day, the agent also confirmed that she can see the double payment on her side, and I was told that the query will be sorted in 7 days, I was also informed that I will receive an email and I should respond with my account details, and I did exactly that the same day few minutes after the call. On the 30th May I call back to check on my query and I was informed that my account details have not been processed and they will be sent to the relevant department for my refund. I phone today to check how far my refund is and I am told that the refund has been processed but should wait another 7 days. I have never felt so disrespected as a client by how the agents just say " YOUR REFUND WAS PROCESSED YESTERDAY AND THE PAYMENT WILL BE WITHIN 7 DAYS" then keep quiet- how rude and insensitive - especially since I need the money for personal needs. So waiting time at Rain is 17 days for a refund? Their processes need a lot of WORK and I don't understand how they can treat one of their clients like this. I spoke to Chesami Fimawe one of the Team Leaders, and he tells me that he will go check and phone me back before 5pm and I am a bit worried because his knock off time is 5pm. I just want my money Bathong hle and cannot afford to wait another 7 days, I was patient for 10 days thinking they got this, but I see I was wrong, this is really bad and disappointing. Here I am waiting for the call. I need the money for tomorrow and they are telling me stories after waiting 10 days. REALLY DISSAPPOINTING
