Sold me a sim that didn't work in my phone.
-Didn't test my phone prior to selling me said sim.

Told me to wait 1hr~ for "line to liven up"
-Waited 2~ hours.

Didn't work.
-Asked for a refund.

Was told no refunds on pre-paid.
-Called customer service, line was cancelled and a one-time refund was offered because "my phone wasn't tested by the store"

5 days later...no refund. Call customer service who are totally oblivious what the situation is.
-Refund "failed", was told they're resubmitting.

10 days later...no refund. Call customer service who are AGAIN totally oblivious what the situation is.
-Refund "re-arranged".

13 days later...no refund. Tweet customer service.
-Threaten with a chargeback and was told refund has been escalated and they'll personally Tweet me when they know what's happening.

T-MOBILE ARE SCAMMERS. HOW THEY ARE STILL IN BUSINESS IS BEYOND ME. AVOID THESE CLOWNS!
