I visited this store with the intention of making a payment on my BYOP monthly plan, but was informed by staff/employee at this location that they don't accept credit or debit cards as payment (which makes little if no sense, since I can pay my bill with a credit card online, which is what I just did about 10 minutes ago).
If the employees in this store cannot (or will not) handle payments, or at least place a sign on the window stating 'credit/debit not accepted at this location', customers wouldn't need to go into the store at all...
A pretty sad state of affairs, if you ask me
