Mtn customer care disappointment

I called MTN customer care 2 weeks back requesting for assistance with regards my Mtn new app were i play flip n win. Now my data or rewards is not located to my number and the consultant I spoke with she advised to call me back within 7 working days and it passed with no feedback. Today I'm calling to follow up on my query as this is happening daily now my Gems are not the same as it is displayed on ussd when checking on mtn app. So the consultant i spoke with named Asanda she advised that she has to lodge new ticket so I will have to wait again but now it can takes to month without any response as they don't have a system to assist with them as consultants. So MTN SA when customer request for assistance it may takes to months without solving that query and I have lost more than 10GB due to error system on the MTN app. I am so disappointed with MTN and I've been using my number for more than 28 years but now we getting this treatment after being a loyal customer on MTNSa
