I have enlisted my son to assist in the communication with you as a lot of the technical jargon goes over my head.
As mentioned to you all of the emails that I send are being blocked. This occurs, no matter the destination of the email within the U.K. or world wide. What my son sent you yesterday was an example of the rejection notes.
I require this problem resolved on an urgent basis. My business is suffering as a direct result of my emails not getting through to customers & potential customers.
I have attempted to send another two emails without success. This has now reached a serious situation regarding our business communication. I need an answer immediately what is going to resolve this problem.
For your information. I have had call from India informing me they are representatives of Virgin Media & they are calling me to resolve problems on my computer. Has your centre requested someone from Virgin Media call me.
