Failed Service By Thabile Shangase of MTN of Durban Office

I have been receiving text message coming from MTN stating that I have change my banking details and billing date at the beginning of September I then contact the call centre and was given the reference number 1/ ********** 2966 and was advised that my query has been escalated and today 13/09/2018 I realise that my phone has been blocked, again I contacted MTN call centre 135 using a colleague mobile since mine is blocked, and I ****k to an unhelpful, clueless service champion of MTN by the name of Thabisile Shangase who kept referring me to and MTN store stating that she can not assist me course she works at the billing department - This is embarrassing for a huge organisation such as MTN to be unable to tell me which store amended my details by a click of a button, and Thabisile failed dismally to refer me to a department that can resolve my query - A s am authoring this message am receiving a text message from MTN saying that My payment details has been updated as I have requested, and I have NOT requested such.
