Pathetic service. Call centre agents are *********** and don't understand English.

I realized on the 18th of March that I don't have any internet connection. I called Rain and to my surprise found out I did a Sim Swap. I asked them to cancel my sim swap and activate my service again. After hanging up the call I realized that I still don't have a connection. After several calls and speaking to clueless call centre agents someone finally told me that a sim swap can't be reversed. I got the new sim card on Wednesday (22th of March) and called the call centre to activate it. The agent said it will take 24hours for my service to resume. I waited to no avail. I still don't have a connection up until today. I called again today and some supervisor told me the sim swap was cancelled and he will escalate my query. I don't think anyone of these people know what they are doing. I want my internet to work again...that is what I paid for. I am really fed up with Rain. I need someone to sort out my connection ASAP.
