Most horrible service I have ever seen

My other line was due for an upgrade therefore I went to one the Mtn branches at Northgate onthe 6th of November and was assisted by a lady who goes by the name Linette and her Branch manager Kgomosto who were both very friendly and helpful.I opted for the home router the 1TB data deal which was approved however they struggled to finalizing the application due technical errors from their system and I was asked to come back the next day and the error was still persisting and I had to go back home again.Kindly note that the error has not yet been resolved since the 6th November until now therefore am struggling to understand how such a big company like you guys take 2weeks to do an upgrade whilst your competitors it takes them an hour and you still have the guts to call yourself the bhoza network which is actually disgraceful and sickening.I need this issue to be sorted out as am going to escalate it to ICASA as you are not delivering the service you promised to offer your clients.
