Several months ago Lingo added a $10 per month add-on feature to my plan that I have no interest in and did not request. I called to cancel and request a refund. The customer service rep said there was no record of me ordering the add-on and said he would give me credit for the three months I was billed. However, he must transfer me to the cancellation dept. because only they can remove the feature. The service rep from the cancellation dept. (Cate) was very rude and insisted that I must have added the feature myself because they would never add I feature I did not request. However, it is a feature that I have never been interested in (softphone) so I am 100% certain I did not ask them to add it to my service three months ago. When I asked to speak to her supervisor she refused to transfer me and told me there was no supervisor above her. I would warn anyone using Lingo, or thinking of using Lingo, to check your bill regularly. You may find that they have added features that you do not want.
