MTN HAS THE WORSE SERVICE

I am a new customer with MTN. App**** for a contract online. Received the phone today, all is fine. I want to PORT my number from Vodacom to MTN. The sales person I spoke to on the phone said I MUST tell them I want to port BEFORE they activate my sim. I was literally on the phone with MTN for 1 hour and 30mins. Kept being transferred all the time and having to call back. Even spoke to a manager WHO TOLD ME TO EMAIL BECAUSE THEY CANT HELP?? Eventually a guy said he will activate my sim and the port must be done AFTER the sim gets activated but another consultant told me this is not true. I am seriously so annoyed with the amount of time and calls I had to do for a simple PORT and now it seems as if my number won't be ported?? I am literally so upset and annoyed. I'm new to MTN, and this is already the pathetic service I'm getting. I don't want a new number I want my number PORTED yet NO ONE NOT EVEN A MANAGER CAN HELP ME
