Very Unpleasing service from MTN

I contacted MTN requesting them to reactivate my number after paying the contract money I owed, I even sent them the letter from MBD but every time I call they tell me to call their legal department. This is not the 'booza service' we expect. they always send me from pillar to post. I called the 135 number the guy called "Homeboy" very rude, unprofessional and not helpful.
