Bad service. No help for either one (MTN and Altech Autopage)

Altech Autopge has closed down and my Cell phone contract was handed over to MTN. Now I paid my account for March directly through MTN, now I am getting sms and emails from Auto page stating that they will hand my account over because I never paid. I went to MTN and they have confrimed that my payment is showing in their system and they don't understand why I am getting sms's from Auto page as they no longer exist. I was told to call 808, which I did. They in return told me I need to call Auto pages customer number: ***, which i did. That number redirected my call back to 808 (mtn). Now no one can asssist me with this matter... This morning I receive a lovely email from Auto page, again stating that my account is still not paid. When I asked MTN if they did not notify Auto page that the accounts has been paid, I got the answer of "I am not sure." How is this helping. I need some one from MTN or Auto page to call me to sort out this mess... I DID PAY MY ACCOUNT AND I DID NOT CREATE THIS MESS... IF I GET HANDED OVER YOU WILL PAY THE LEGAL FEES NOT ME AND YOU WILL CLEAR MY NAME..... YOUR SERVICE ARE VERY POORLY
