Diabolical service MTN

MY Samsung S5 was ****** on the 9/9/2015. It is insured with Mtn. I went to the Cavendish Squre branch the next day and started the long arduous process of filling in forms which were returned to the Mtn Cavendish Branch on the 11/9/2015. It must just be said that you cant Phone the branch, you have to go in personally to get anything done. Days later after having been there five times, with them loosing my forms, giving me incorrect information making me jump through more hoops the manager of the store finally admitted to me that Mtn were absolutely useless and that it was near impossible to get through to customer care and especially the business section and that he thought I might never get a cell phone out of them. After many failed attempts to get through to Mtn customer care *** I have tried again today 25/09/2015. After listening to Mtn and exceptionally irritating music for 25 min I finally got through only to be told I was being transferred to the business section. 88 min later still hanging on...Will try hanging on for a while longer. I do not know what to do or were to turn to. This is insane, what a terrible service provider to have. Close your doors down
