BAD CONSULTANT AND SERVICE

2 months ago my phone was ****** at work and reported it, luckily I found it, but I already blocked it, I`ve asked mtn call centre to unblocked it but nothing happened, firstly they gave me a wrong fax no, I tried several times , eventually spoke to 2 consultants , nkululeko mhlongo and nokukhanya ndaba, they both asked me to email the relevant documents straight to them , which I did and im still waiting for an answer, until now no one bothered to come back to me, im still waiting, but they say their job is to serve customers , aint I a customer? or is there a waiting period for the phone to be unblocked or I must just forget about the phone ,if there is still hope, for this IMEI *** CELL NO *** ILL BE BACK ON AIR SOON
