Rain 5G pathetic lack of understanding

I am very disappointed with Rain 5G. I called to register a business account with them only to be told it has to be done in my personal name. I provide them with all my personal details including my ID number. Long story short, the delivery arrived the day before I was scheduled to go on leave. Yes I was ready with my ID and proof of address. I was away for a week and upon my return was told by the staff member who had set it up that the 5G card couldn't fit through the slot. Once I inspected it I realised that it had not been cut to the right size. I called Rain and informed them. The gentleman I spoke to (forgot his name) told me that they would arrange to send a replacement card. 2 weeks on we still hadn't received anything. I made another call, this time I was wise enough to take the name and ask for a reference number for my call. I then received my email to schedule a delivery booking with CCD courier of which I did for the following day. Ok so even though delivery was scheduled for between 8-10a.m. I got a call to say the driver would be running late and would arrive by 12p.m. of which I had no problem. The driver finally arrived at 1p.m. Now unfortunately I was ******* incidence a few days earlier and in my bag was my ID. So when the driver arrived I explained I had my ID copy as I did not have my original and he unfortunately took the card back. I called Rain to explain my situation only to be told there's nothing they can do to assist me if I don't have my original ID, needless to say, the reason I am now being inconvenienced is for no fault of ours as a company nor mine as an individual, but rather its Rain's fault that they initially sent us a faulty sim card to begin with. Now our company is being punished because I was ****** and Rain doesn't care. I asked to speak to a supervisor and was told there were 2 supervisors, 1 was out of the office and the other was too busy to speak to me. . . . I am appalled by their disregard for customer service.
