Bad service

Yesterday I arrived at Mtn at 14:20 to upgrade but really down grade the a data bundle of R99 plus router. First I was told that the upgrade was not due. Had prove on my cell. Secondly my application was declined because of a wrong address - after being with this service provider for more than 15years. Thirdly my application was declined for the second time - why????? because I had an amount outstanding from last month in the amount of.............. ....... R1, 30. Eventually I paid this huge amount plus the bundle of R130. 30. The last straw was when they app**** again and the application was declined once again . By now it was already 17:15. I was told they will sort out the problem today, because yesterday it was already 17:15 and they close at 18:00. I phoned at 11:30 and they told me the consultant that was dealing with this matter is busy. It is 12:00 now. I am still waiting.
