No customer Service

I am not happy with the customer service from Rain, my wifi has been off since Sunday afternoon and until today I still don't know or understand why my wifi is not working. Also they don't call or inform me if they are working on my query I must keep on calling them and the call centre staff is very rude. I have requested for a supervisor or manager to call me yesterday already and still nothing. How can you treat your customers like this? What kind of service are you providing? Why is there an online portal with messages and notifications if you don't even use it to inform me why my wifi is not working? I will suggest you use your online portal to communicate seeing your staff is *********** in doing it. Please note I will lay an formal complaint in the next 24hrs with the Obudsman if my wifi is not sorted.
