Rude, ***********! BAD service!

Have been with MTN since 1994, but rest assured I will gladly stop being a customer on 16 March 2020! I have been billed for "Content Charge" as follows: R259.03 in December 2017, R285.05 in January 2018, R500.08 in February 2018 and R255.04 in March 2018! NOBODY can tell me what this charge is and who authorized it - it was not me! And this despite the fact that my usage limit on my account was set at R 500.00! And then I update my contract on Monday 12 March at MTN the GROVE in Pretoria, but their systems were down so they they NEVER processed my upgrade. They phoned me yesterday afternoon 15 March to tell me that my fingerprints "did not take". So I went back to the store this morning 16 March (my time, my petrol...) only to be told by a very agitated employee that I did not do my fingerprints on Monday! When I told her that this is not true and retold the whole story about their systems and even the photocopier not working on Monday she became rude and insisted on showing me on her computer that "it says cancelled". I then became extremely irate and demanded to speak to the manager who then told me that if an upgrade is logged on the system but not processed within 48 hours the "system" cancels it. Except for being called a **** to my face I was even told that I should have gone in for an upgrade on an earlier different day! NONE OF THIS was my fault! All of this is due to the UTTER INCOMPETENCE of MTN, its agents and staff! NO APOLOGY!!! Just rude accusations blaming the customer! I should have cancelled my contract there and then but I have been loyal to MTN for 24 years. Well, NO MORE!!! If MTN wants loyalty get a dog! It is time that MTN realizes that they are NOT the only service provider and that competition for business is tough en getting tougher. I WILL be moving to another service provider on 16 March 2020! I have spent more than R 150 000.00 on MTN since 2010 only! (At one stage I had 3 contract phones - now I have 2). BUT apparently you do not like me as a loyal customer, so fine - you will be rid of me in 2 years. I can't wait. For me it will be good riddance to BAD *********** RUDE service!
