Contract Troubles

I went into store yesterday at 14:00 at clearwater mall to apply for x2 IPhone X’s mobile contracts that’s R2000 rand monthly excluding any additional costs and it seems as though my buisiness isn’t valued I was told that my documents would be send through and once approved I could collect my devices yesterday, when I queried with MTN customer care after being put on hold for 15minutes they told me they can’t find any records of the device concerned as I received no texts messages I went back into store at 8am at your Clearwater express store they lady then only advised me that my application wasn’t being processed and the proof of address with PO Box wasn’t sufficient another thing i’m Struggling to understand because as per FICA a letter from a financial insurance with P.O. Box is acceptable as long as it has your name on it which it none the less my application was sitting at incomplete and no body bothered to liaise with me, Having no other documents besides my bank statements and all other statements with my PO BOX address. I came back to the store and provide my sworn letter stamped by the police station confirming my physical address and the friendly lady their told me it would now have to be processed again. This is unacceptable I made it very clear that i needed the devices today, The lady informed it may be done today. The only reason i chose MTN as a service provider was because my company has all our contracts out through MTN and if this is the service received I guarantee I will take all my buisiness elsewhere.. My bank statement as well as investment letter all use the PO Box address. I can’t understand what the hold up is regarding my approval since during credit vetting I would assume it would be know that I have bank accounts with over R3million in and an impeccable credit rating in addition to that I receive more than 30k monthly reflecting on my bank statements The reason I app**** for the contracts is the need for the mobile numbers with the devices... It baffles me that other applicants with a salary of R3500.00 are processed immediately without any issues. I feel that MTN Has no sense of urgency in dealing with and I would like to be assisted with that matter immediately. I would like to collect my device todayz
