No assistance from MTN

Upgrading your phone only comes around every second or third year, which is supposed to be an experience, not true??? NOT TRUE, somehow we got to deal with MTN Cosmo Mall and the customer service is up to ****!!! Contact numbers listed for that branch exist but doesn't work. The salesman responded to 1 of my emails and customer services asked me "so what would you like me to do"... Paperwork from our side has been signed and accepted but according to DSV (the courier company), the phone cannot be delivered until MTN Cosmo approves the recievers contacr name and adres. It's been 3 days and has still not been done by the salesman nor any one else at MTN. DSV said I should phone MTN and request that they do it but if I can't get hold of Cosmo, *** should I do? Hats off to the hand full of employees that actually tried helping-you guys shine above the rest!!!!!
