Exceptionally Terrible Service

Hi

I must say am very disappointed in the way MTN has become have been a loyal customer on contract since 2013 and not a single month I missed on my payments ,of lately decided to get an additional contract of which app**** last week Tuesday in store at Rosebank Mall ,since last week been asked to send a copy of my old passport I opened the bank account with I have sent it on Thursday .My surprise when I follow up they say its processing only yesterday they say it doesn't match with my current passport number of which the old and new passport number cant be the same ,I have been using the same bank account and the MTN debit orders run on that exact account .
