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.

Poor customer service. I couldn't understand the customer representative. He asked me the same question 6 times!!!!! I still don't have my refund because he claimed he couldn't understand me. Same problem with another customer representative. She passed me off claiming she didn't handle that department. Next person was not nice at all

Selling Bad Codes + Failure to Communicate Ordered 6 monthly refill pins. 2 worked, the other 4 did not. Attempted to call, and line does not even connect (despite claim of 24/7 service). Sent in Online Form, received receipt, never contacted again. Called again 2 weeks later, customer service rep knew nothing about complaint, resent receipt. Now dealing with same issue a month since with no response, and their customer service line cuts off after 50 seconds (exact) of hold jingle. Having to demand reimbursement now from credit card company as merchant sold faulty merchandise and is not communicating to resolve issue. Would recommend purchasing else where. Sad that this occurred after a year of appropriate transactions.

Here's an update on my latest review Here's an update on my latest review. Ana from customer service hung up on me when I confronted her about the $33 pre-auth hold. She said she will only refund me $3 out of the $33. I'm considering taking them to small claims court.

No longer the best price I have been purchasing my T-Mobile pre-paid SIM card top up from Callingmart for the past several years. I started buying from them because they had the most competitive price. But it is no longer the case. Since last year, I have to pay the full face value plus $2 fee (required by T-Mobile according to Callingmart). I can get it from any other online seller for the same price and even from T-Mobile website (have to pay sales tax but not the $2 fee) with he same convenience of online shopping. I probably can go to one of those small Mom&Pop telephone store and get it with a discount to face value (+ sales tax) if I look hard enough.
