How to cancel Carly subscription ⁉️

User reviews

Scam

I am extremely disappointed with this situation. I requested a refund for the charge of $261.47, but my request was rejected. I believe I have been unfairly charged and I feel that I have been misled regarding this subscription renewal.

I was not aware that this subscription would renew automatically, and I did not intend to continue using this service. Being charged $261.47 without clearly understanding that this was an annual renewal has caused me financial loss.

I believe this situation has been handled unfairly, and I am requesting a proper review of my refund request. I ask Apple to investigate this matter and reconsider the refund decision.

Warning beware the auto renewal

Normally never leave reviews but I have just been stung with the poor customer service and auto renewal scam this company runs.

Don’t bother unless you want to be paying money every year without a chance to get out of this product.

You have been warned

Be warned

If this product does not work, there will be no refund at ALL... There is no way to contact them, other than automated response.. Also this is a subscription.. You will be charged every year... Please buy a cheaper device that work, as Carly is a brand that cannot be trusted & is only after your money...

Update: Amazing that Carly seem to think not answering your questions is acceptable, as long as they reply to them even if they do not answer the question asked.. Looked all over the internet and seems with carly, if the product does not work... Then the answer is tough luck mate... We do not do refunds regardless.. Unless anyone can prove me wrong...

Difficult to cancel subscription

This company uses dirty practices to make it difficult as possible to cancel bloated overpriced subscriptions. You don’t get notifications or receipts. They don’t even add new features (for older cars, idk about new ones), what the heck are we paying for? Avoid!!!

Edit: they did the right thing and refunded me.
