I have been a loyal myn customer for 4 years i literally converted to mtn from Vodacom due to the high praises and good rates Mtn offers. although now that has seemed dismal, i am due for an upgrade since last year but was waiting on the Samsung6 edge i put my name down on the waiting list in March we in JUly still no phone or communication about it bare in mind i have visted MTN IRENE several times to ask about phone and get told different stories to the point i changed my upgrade to an s6 and was promised will be called in a week still nothing and we in JULY? in APril i app**** for a laptop additional to my 3 contacts i have with MTN to this day i am still waiting on if it was approved or not ..Mtn irene has poor services and has made one reconsider moving over to cell c as of the bad service i have been receiving from MTN IRENE...mtn please resolve this matter??
