It was terrible after debited my account twice and i called call center to resolved my issues they promise that they will call me on monday but until today no one call me. I have to call them again to follow up with my refund, the agent who answered the phone told me that it was a system. i asked the manager but the manager didn't take my call instead told the consultant to explain to me how long will take my refund will to be debited into my account. I ve been loyalty customer for rain quite sometimes now but the customer service i experience at rain this time was shocking i will wait until month end to finish my subscription and find another network provider I am disappointed about the way they handle my issue and monday i have to called them twice i bought airtime twice so that i can able contact them. Their service is terrible and i will never recommend rain to anyone. If the manager respect the client he was suppose to take my call and understanding my frustration and why i was asking him
