Upgrade 10 days later NO DELIVERY NO VALID EXCUSE

I app**** for my upgrade through MTN Direct on the 6th of November 2015. According to me my application was successful and the consultant confirm that I must please remember a copy of my ID as well as a proof of address.<br> On the 9th of November 2015 no delivery no phone call. On the 10th of November I phoned and got to the Kwa Zulu Natal branch according to Alicia there was a rejection but the sales rep that did my upgrade must fix it she will mail him and supervisor to pls fix and contact me. On the 12th of November 2015 I phoned again because still no feedback or delivery I spoke to Annelize this time the excuse was that there is a delay in the delivery's in Gauteng. Again she will get a supervisor to contact me. On the 16th of November 2015 I phone again according to Lalicia still the same delivery delay in Gauteng, again will get a supervisor to contact me. Still up until this second no supervisor phoned me at all. Also no delivery. I think this is the worse pathetic service that I've ever got in my whole life as being a customer from MTN for the ? 17 years. Can I please receive a positive feedback or else I will have no other alternative than to cancel my contracts
