I am writing to express my dissatisfaction with the recent customer service experience I have encountered over the past three weeks. The primary issue I have encountered is the lack of effective communication between departments and the prolonged duration of my ongoing query resolution. Despite multiple attempts to seek assistance, I have found myself repeatedly passed from one department to another without achieving a satisfactory resolution. Furthermore, there were instances where I was placed on hold, only to be advised to wait for a moment while your representative sought confirmation from their manager to update my account. Subsequently, I was transferred to a different department without any prior communication or explanation. I have also received assurance on two separate occasions via phone calls that my issue would be resolved, with the expectation that it would be updated in the system. My initial concern pertained to the absence of insurance coverage following the change of ownership of my phone. However, upon subsequent inquiries for an update, I encountered a lack of awareness regarding the matter. I was informed that they would need to review the phone call records, but I was also advised that the likelihood of a resolution remained uncertain.
