RAIN - beware! - bad service

I have written a review about the bad service of Rain a while ago. At the end of September a technician came and recommended that the contract is cancelled since there is no reception. This was done, the appliances and sim cards were returned etc. I was told at the beginning of October that a refund of my fees will be made within 5 days. It is now nearly 3 weeks later. I contacted the Rain support on the 19th and was told that no attention was given to my case up to now.
