Not only are the wait times extremely long to get someone to speak to, I had to call customer service tonight, which is a 24 hour service hotline, and after waiting on the phone for 1.5 HOURS, they hung up on me saying to call back later. Is this how they treat their customers who need these devices to work!??? OMG, this is awful. It was just her sensor, but what if it was her insulin pump that stopped working??!!! This is horrible. I'm seriously considering leaving this company now. What other companies have better customer service (are there any??). This company makes so much money and I cannot believe they don't have enough people to take orders, or help others. In any case, my enlite sensors keep dying early in the week. I think there's something wrong with the transmitter. Can anyone else get a hold of them at off hours, or am I the only one with such bad luck? Thanks in advance.
