Struggling with an upgrade since 20 August15

Dear Consultant , Ive been struggling since 20th August for a simple upgrade by MTN .At first I was told that I am corporate and the courier will deliver the handset within 5-7 working days .I enquire on the 28 Aug.15 and were told that its been preapproved . Make a follow up again on the 1 Sep and visit the MTN Head Office on the 2nd Sep .They only then realized that I am not a corporate customer and say that I can collect the handset at MTN Menlyn ,Got to MTN Menlyn to collect the handset on 2nd Sept.only to find out that there is an error on the system and they cant handover the handset .Visit MTN again on Monday 7 Sept,could still not collect the handset .MTN most famous phrase are : Its been escalated , this matter has been escalated for more than 6 times and still no handset .I got 3 contracts with MTN and are looking around to other service providers that would value customers and I hope the broader public take note of these shoddy service from MTN .I am still waiting for the handset
