Rain sells poor connections -Service is below the ground!!

I dont know where to begin with this horrible service , I cant do anything or connect simultaneously just with my phone let alone 2 or more devices ,everyday is a struggle the connection is poor and gets worse everyday ..it is nowhere 4G connection shame I am so disapointed!!! The monthly deductions is not worth it to be honest its like you are paying for a shared service that you need to berg, for someone working from home I just cant anymore....Rain must be cancelled!
