Judgemental blessings

Wednesday I get a call from and politely using my airtime, not a land-line, I call back and I'm told it must it's Mtn Maverick and asked if I have an account / contract with Mtn and say yes. I'm told its the retention department and they'll put me through, which they do and I get through to voicemail and leave a message. The next day I get a missed call again and I again, I wafted airtime calling and get through to Mtn maverick and explain what happened and enquires why no voicemail was left, I mean, is that not the reason we have that feature, cos had a voicemail been left, I would not have needed to waste airtime I will not get back to return the call. Today at 9am just as I wake up I get a call from them again but luckily I was able to yahe the call and speak to Demi-Lee Brickwa who explains to me that I'm up for an upgrade and tries to sell me specials they have available and as I just woke up, I couldn't really pay attention and ask her to email me. She emails me the specials and the handsets they have doesn't interest me, so I go to the Mtn Store in Gardens Centre at 6pm and I merely just wanted to roam to see if they have the new Sony flagship Compact handset and before even answering it checking he tries to get me to take a Samsung, what happened to listening to your customer and providing a service to the questions asked and enquiries made?! And I walked out of the store as I clearly was not heard and my need not taken care of. I've been with MTN on this number since 2002 and you can see I've always only had a Sony Ericsson, with the exception of the phones before the Sony Ericsson was launched, which was the white and orange Walkman handset. This entire week my time, effort and airtime was wasted, not Ayoba
