POOR MTN SERVICE

I've recently (19th April 18) app**** to upgrade my MTN contract online. But to date I've not received my devices. I've been calling MTN call centre(135) from the 26th of March to find out what's happening with my devices. I was told that my surname had been incorrectly spelt and the when they left the warehouse to the delivery company and that they had to return the devices to the warehouse because of this error. I called the call centre again on the 29th and 30th but with very little assistance. Nobody could give me proper answers and I was transferred from one department to another until I was told that the warehouse was closed and nobody was picking up the phone. I sent an email to the customer care on the 30th and received and mail back apologizing but still no action was given. I was given a reference number( ********** 4) which means nothing because nobody contacted me after the 30th to inform me what was happening. I called the call centre today, 7th May to find out what was happening and I was finally told that they are trying to cancel the online upgrade and that I need to upgrade in-store or over the net again(something I will never do again). The main problem that I'm sitting with now is that they will charge me twice and upgrade fee. I've been with MTN from 1998(pay as you go) and I've been on contract from 2004 (italk cellular, MTN Direct and now MTN) to this year. How can a service provider spell your details incorrectly when all your information is on the system from 2004( 14years) but they are quick to remove your limits and increase your billing. I've never been more disappointed with MTN as I am right now. Now I have wait ( no sure how long) for them to cancel my upgrade before I can go into the store and do a proper upgrade. I'm actually thinking twice about using MTN again... I was on a telephonic survey in early April and I gave MTN good review on there service delivery had I known what was about to happen I would not have done so.
