I've received a letter from Lowell… I've received a letter from Lowell about o2 debt that doesn't even exist as I haven't used o2 for ages. I never received any letter from o2 about an outstanding payment. The letter letter from Lowell doesn't provide any explanation. Tried to contact Lowell but there is no email, including on their website and im not going to call them and wait and be charged for nothing. I have contacted o2 and they told me my account was closed in the beginning of 2017 so almost 7 years ago!!! They (o2) were not able to tell what was the reason why Lowell sent me the letter. So I wrote a complaint to o2 and after that will also make a complaint to the financial ombudsman as it is very stressful to me. Looks like o2 together with Lowell does it to many former customers now as I found the same complaints written by others.
