Unproffesional

i went to MTN head office on the 25th of August regarding refund issue, was assisted by Nomvula Zwane from Legal she promised that i should expect my refund in 7 days and gave me her numbers, 2 weeks passed with no action, i sent her emails, sms and calls with no response then went again on the 13th September and was told my query is with refunds and banking was assigned to Stephen Ramage he said i must expect payment that same day or the following day, tried to call him, sms and emails no response still and he's the one who said i must call him if i haven't received my payment. i called head office again on Friday and requested to speak to him, was given his junior and was told he's out of the country it was so unprofessional if he left country without resolving my query or assign it to some1 else, the lady i spoke to told me i should expect my money on Saturday since they use Standard Bank and i use FNB, i waited again for nothing . i was supposed to drive to Mafikeng on Sunday since i have a wedding on the 22nd September but had to postpone my trip. Tomorrow morning hoping to talk to their seniors regarding this and want my money immediately.
