Rip off I bought what was supposed to be an unlimited talk and text, 3gb H20 card from them. And after all the b*llshit of verifying my address, and not getting the email with my pin in it until I emailed them twice about it, I logged on to H20 to use the pin I got and all my data was gone but 500 mb! I called customer service to get it fixed and they said that there's nothing they could do. Callingmart bought a $35, 500mb card and advertised it as the unlimited talk and text, 3gb card. Now I'm f*cked out of all my data until next month.

I use their website and I signup for… I use their website and I signup for Auto pay(since 2016) , but when the due date of my auto refill they failed to keep my account active than when I called the horrible costumer service they said they cancel the transaction with no further explanation and no apology. never again loser

Stay away from this company - Broken Website Stay away from this company, Callingmert. Their website is broken all the time. They will take your money, put a hold on it, then they will send you an email stating that your card is out of stock and will take a week to release a hold on your money. This happened to me 3-4 times already. Their website is broken 9.8 times out of 10.
