Not sure what you mean about the last name, I'm saying that doing a chargeback is likely cause for PM to close the account. Doesn't matter about names, cards, whatever.
Moving forward, it seems to me you have 3 separate but related issues. If it were me, this is the order I'd want to resolve them, realizing they may not all be fixable. I used to have a boss whom I quote a lot, "there are 2 kinds of problems in life, small problems and big problems. If you can solve it by throwing money at it, it's a small problem. If not, it's a big problem." (the latter could be because money won't solve it, or it could be because one doesn't have enough money needed).
1. No service. You need data (and maybe voice and text, or maybe you get those through data). Fix for this is to sign up as a new customer: new email for the account, new phone #, new SIM new payment method (or vouchers). The SIM and vouchers you bought recently may or may not meet that need (depends whether they're considered burned off or not). See paragraph at bottom starting "Finally" for another suggestion related to this.
2. Loss of the recently-purchased SIM and vouchers. Maybe they're still valid because you were trying to apply to previous account and it didn't work, or maybe they're not valid because they were used far enough into the process that they're now considered used. You could pursue with PM about it (through CS Agents) but that will take time and might or might not be successful.
3. Loss of previous phone number. I assume that if a customer does a chargeback with the bank (credit card), that PM closes the account (just my assumption, mind you). You could pursue this with PM (through the CS Agents) but again will take time, and I'm not sure you'll have any luck with it.
Those are my thoughts, I don't have any insight into this. If you were a friend who walked in and said they did a chargeback on their prepaid mobile because someone stole it and was making purchases, I'd give them the same advice, though it would be a bit easier to identify and timeline and who's involved, in a F2F discussion.
Sorry I don't have better advice, but I sympathize and I do understand you have no WiFi at home so you need some sort of data. That's why I'm saying get up and running somehow fastest, then deal with the money (easy to say, it's not my money, but as I said before this is how I would tackle it -- treat as 3 issues and beat each one in turn).
Finally, consider doing step 1 with another carrier. Then when you tackle the other issues, you won't run into confusing PM between your old and new accounts. Freedom advertises $34/50GB or $29/20GB ending today (Nov 29). No idea how to sign up with them, nor how good they are. Lucky is also still pushing BF, and you can get SIM cards at Dollarama and WalMart. Then if the dust settles you still want to come back to PM (or if you somehow manage to retrieve your old # or Rewards, say) you can switch back to PM if it suits you. If you're going to end up losing your # and your Rewards, the world is open to you (sorry, trying to find a silver lining in this very dark cloud). And you can decide which "friends" get your new #. 🙂
[The foregoing should not be taken as a general recommendation to switch carriers even temporarily, but in this case it may be warranted.]
Hope this helps.
