bad call and service from FNB connect

just want to say i am highly disappointed at the service i got from FNB connect who called me and offered me a 1GB data package which i said yes to because i spend alot on prepaid data thinking it was going to be to my benefit but i was wrong.i asked for my number to be ported and was promised it can be when i spoke to the consultant, the sim now was delivered with a new number and when i called to inquire i was told now this is not possible to top that off nobody told me that my account will debit when i receive the sim card almost TOTAL of R89 then R143.17 ALL ON THE SAME DAY i am ****ed because if i knew that i would not have taken this because it was not explain to me..i want this cancelled and my money back this poor service from FNB and will be cancelling my bank account aswell somebody better reverse my debit and collect this sim from office as i don't need two different numbers had my ********** 428 for over ten years now i will be cancelling everything
