Quick to take your money, but wait forever to get it back!

Mondo call center agents are very helpful and efficient when you want to take out a contract with them, but when you cancel a contract and return the phone within the cooling off period it takes forever for them to process the cancellation! It was supposed to be taken care off and refunded in 2 weeks and that was over a month ago and I'm still waiting! I cancelled the contract in February yet I'm still being billed for it! I've contacted the call center numerous of times! One was so rude she put the phone down on me when "putting me on hold to look up the contract". Now I can't even get through to an agent!
