T-Mobile customers love their pizza very much. A little too much, perhaps.

After just two T-Mobile Tuesdays, the Un-carrier’s pizza partner Domino’s said it is discontinuing participation in the promotion.

According to T-Mobile CEO John Legere, the decision came after Domino’s was pressed to meet an overwhelming response from T-Mobile customers that boosted volume to three to four times the regular daily amount. Legere said Domino’s wasn’t able to fully keep up with the demand.

“Basically, @tmobile customers love @dominos pizza so much, you broke them!” Legere wrote on Twitter.

In lieu of pizza, Legere said the Un-carrier will be thanking customers next Tuesday with another free ride on Lyft. Legere said the voucher would carry a $15 value.

Legere said T-Mobile will also offer customers $20 of “free stuff” from MLB.com. The Un-carrier will continue to offer a free Wendy’s Frosty and Vudu rental as part of its T-Mobile Tuesdays giveaway, he said.

Since the launch of the program nearly two weeks ago, Leger said the T-Mobile Tuesdays app has been downloaded more than 2 million times. Legere called the program a “massive success” and said T-Mobile already has new partners lined up. Those partners will be announced “soon,” he said.

The Domino’s decision is the second hiccup T-Mobile Tuesdays has faced in as many weeks.

Last week, the sky-high traffic from customers trying to access the T-Mobile Tuesdays app crashed T-Mobile’s servers, leaving many customers in the lurch for most of the day. The issue was fixed the same evening, just in time for customers to claim their free pizza for dinner.
