My rain poor aftersales service

I must say I am very disappointed with Rain, called them for a few days to cancel but there was no response, I left a message for them on my rain support, no one came back to me, I finally spoke to one of their sales consultant who was so quick to transfer me to the support department after I had explained how I had been holding on with no answer. I mamahed to get a hold of this gentleman from support after a long hold, explained my issue, the gentleman advised that HE WILL ESCALATE AS AN EMERGENCY AND GET THE RELEVANT DEPARTMENT TO CALL ME...but nothing I am still waiting and I want to cancel and want my refund as quick as possible
