On the 23rd of September I decided to switch to rain from the network I was using but the service was so horrible becoz they didn't activate my network even when I called for assistance. Then on the 15th of October they debited my money knowing very well that I told them to cancel my package , then they debited it again in November . When I asked for a refund they kept coming up with baseless excuses.
