Horrible customer service, rude and *********** staff and a bunch of *****s

Mtn Bloemfontein, Nelson Mandela drive has the most pathetic service ever, So my mom is a pensioner who has wifi contact with mtn, It's been 6to 8 months since she has been taken from pillar to post ,on the initial contract the paid 720 and the agreement was that monthly she will pay 400 , to her greatest surprise mnt still deducted 720 plus the contract money she askes them to refund the 720 that was paid prior and was told they will allocate to her account, the person responsible of transfers was Michael who i believe did not allocate accordingly thay why we sitting with this problem .. till today nothing has happened she has been going to mtn to follow up atleat twice a month with her expenses and sending what's up messages which the response is extremely rude by a lady called Portia ,Portia is doing nothing and she constantly responds thay there is nothing she can do she is waiting on the ticket? Like mtn for 6 to 8 month u sitting with an extra 720 in your account and u do nothing about it or is that how u ***** money from people? To top it all today my mom sent me another screenshot with Portia responding thay she can come speak to the supervisor, This is an elderly citizen you guys can't even be considerate? And who pays for her petrol each time to ask questions? This is not acceptable and Portia and Michael are extremely rude and ***********, Mtn I want thay money refunded immediately or we escalate further so it's paid with interest?and petrol cost and data as well as airtime?

This is not acceptable I want this resolved immediately that money has been sitting for a long time in your account and it's obvious thay the Auditors are also kot doing their job as well as account department and finance Call her Portia know her number and details around the issue she has been a customer for more than 20 years and it's hard for her to even change parckage but I believe as soon as she get her ****** money she will move and I will make sure she moves to another network also to spread word of mouth still this is pathetic Thi
