Three UK Customer Service Issues

I encountered difficulties canceling a 4G mobile internet contract that I initially cancelled in store. After being directed to cancel over the phone and then back to the store, I faced obstacles and even verbal abuse from staff members. Ultimately, I successfully cancelled within the 14-day cooling-off period via online chat and returned the 4G device to the store. However, I am now being harassed by debt collectors for a disputed £[redacted] fee due to the poor signal quality in my area. Despite efforts to resolve the matter by contacting the shop or the phone support, I have been caught in a frustrating cycle of redirection. The shop claimed their systems only retain records for 6 months and were unable to assist, prompting me to consider escalating the issue to trading standards.

Earlier this year, I fell victim to a scam where someone impersonated 3 for an upgrade call. Though I realized it was suspicious and hung up, I inadvertently shared some personal details. The scammers used this to open a phony phone contract with 3, which was promptly canceled with no payments made. However, the fraudulent account still appears active on my credit report, showing arrears and missed payments, harming my credit score. This issue could impact my future mortgage rates. How can I have this false information removed from my credit report to resolve this situation?

Earlier today, a £9.78 transaction appeared on my account unexpectedly. I recently cancelled a contract with Three Mobile and settled any outstanding charges as requested. Surprisingly, my account was closed without receiving a final notification from them, which contradicts their usual practice. I am seeking clarification regarding the £9.78 deduction and I am hopeful for a prompt and professional response from Three Mobile this time. In the past, my attempts to contact them through calls and messages have gone unanswered.

When I signed up for my contract, Paramount Plus was supposed to be included. However, I have been unable to access it despite several attempts. Whenever I try to log in, I am prompted to start a new plan with them. Despite reaching out through live chat multiple times, I have not received a resolution other than being told I should have access. What is the point of having a plan if I can't even use it? While I appreciate having access to Paramount Plus, I have yet to successfully sign in. Any assistance in resolving this issue would be greatly appreciated. Thank you. Avril
