My 88-year-old mother, who is hard of hearing, visited an Optimum store on 2/12/2026 solely to…read morecancel he landline phone service. During the visit, sales associate Ronald B told her there would be a one-time deactivation charge related to her phone service cancellation. Instead, without her request or informed authorization, he signed her up for Optimum Mobile service and activated two mobile lines. Reference information: Mobile Reference: 88798065 Transaction Number: 2018195 My mother did not request mobile service and did not know that she was being enrolled in new cellular accounts with recurring monthly charges and activation fees. She was subsequently billed: Activation charges totaling $51.92 Monthly charges of $43.48 for February 2026 Monthly charges of $43.48 for March 2026 Monthly charges of $43.48 for April 2026 We repeatedly tried to resolve this directly with Optimum customer service. I personally spent 1 hour and 40 minutes on the phone, speaking with two billing associates before the call was disconnected. Total, I have spoken with six different representatives, including three individuals named Ahmed, without resolution. In addition, my mother went into the Optimum store on Mamaroneck Avenue in White Plains to resolve, three separate times. Finally, on the last visit, they gave her a number to call to resolve. This situation is especially concerning because it involves an elderly, customer who appears to have been misled during what should have been a simple landline cancellation visit. We are requesting: Immediate cancellation of all unauthorized mobile services Full refund of the $51.92 activation charges Full refund of the February, March, and April monthly charges of $43.48 each Written confirmation that the account balance is zero and closed A formal review of the sales practices involved in this transaction. Each person tried to keep us enrolled, even when I mentioned possible fraudulent activity where I am sure the associate received compensation for his actions. We believe this reflects deceptive and improper sales practices involving a vulnerable elderly consumer. When I called back I talked to Jana who informed me that a credit would be coming within 24-48 hours. The number of people I had to repeat my mother's story to is ridiculous. I asked to speak to a supervisor and was never connected to one.

Second, our phone quality was awful. We couldn't hear anything. Technicians told us that our connection was insufficient, and we would have to buy another connection for $500 a month. Total comes to $886 a month, for something other companies charge less than $100 for. They sent me a technician who introduced himself as "Cheese". He was extremely unprofessional. He mocked my office, my company, and our equipment. His cell phone blared throughout my whole building, playing a "ringdingdyding" childish ring-tone fit for a high school freshman, which he took the call in the middle of our meeting, loudly bragging that another client had insufficient service but "too bad for them because they signed a 5 year deal haha!" and then told me "they're in the same boat as you". Awful. Despite all my complaints and problems, that were never resolved, they still had me on their list of customer references.
