Horrible service, was refused manager escalation after many calls!

My internet was disconnected on the 07 May although I made payment by the 26th April, upon calling Rain I was met with extremely poor service, to top it off the consultant was rude and would not allow me to talk, she kept talking over me constantly, I called again and the second consultant was very nonchalant, kept giving me an irrelevant answer saying I must be next to the router so that they can do troubleshooting after I expressed that there is nothing wrong with the router they need to reconnect me. I then asked to speak to a manager and I was told NO I cant and wont be able to, this shocked me. The level of poor service, rudeness and simple not understanding clients queries and flawed billing system at Rain is disgusting and cancelling is impossible too. I am flabbergasted as I use internet for so many business related things and now I am highly inconvenienced, I was promised I would be sent an email with the steps and hours later nothing! tis is ********** !!!!
