Trouble registering on website

I have had trouble registering on the website from the very start and I have now made numerous call, sent countless emails and even received a confirmation letter stating a change in cell number and yet every time I try to register your website tells me that my cell number is different from what appears on the system.

Now please I urge you, can you please look into this and fix this. We are in a time where we are able to manage accounts online as we don't have time to send mails and make phone calls, I would really like to also have this experience.

Look into this as I am really tired of trying effortlessly to correct this while every attempt seems to fail.
