I JUST WANT MY NEW SIM CARD. How hard is it to replace a SIM card?

I contacted rain on Sunday which was on the 2nd of July. Then called again to find out the progress of the delivery on Thursday unfortunately I was on hold for a very long time until my airtime finished. Then I contacted them again on Friday which was on the 7th and they said they'll escalate it but I did not receive any call from them or any other form of communication as per their promise since their calls are recorded. I was promised some communication regarding when my delivery will be made. Rain does not care about their clients. Also I missed out on the whole week of using my data. I wanna know how that issue will be resolved regarding the week I missed.I lost my SIM card on the 1st of July so I reported to do a swim swop on the 2nd of July and today is the 10th of July, I still did not receive my SIM card. I called on Wednesday to find out the progress of my SIM card and they told me that the SIM card is still pending but they'll escalate it. They said I should get it on Thursday or Friday. I've been calling rain and everytime I get a different story. It's so frustrating because my issue is not being taken serious. I use the data for School and I've been using my own data. That's another expense on my side. I've been understanding your your delays and backlog but as a rain client I also reserve my issue to be sorted out. What I wanna know is when is my SIM card gonna arrive?
