TELKOM APP AND SERVICE MAKES ME WANT TO PUKE!!!

Telkom APP = Trash!! I was buying data using the app. I get an error and keep trying. I tried about 6 times and while I was getting errors data was being allocated to my account. I realise that while was I was getting the error they were busy allocating data to my account. I ask them to reverse the data. They log a query. I wait the whole month and a few days for feedback. A month later I call they tell me they resolved my query I will not get a refund. they sent me an email on the 12th I've depleted the data. I log a query on the 25th and on the 12th which is almost three weeks they expect me to still have the data wow!! This is the worst customer service ever how am I as a customer supposed to keep using their buggy app. Now I am worried I will owe them millions trying to buy data getting errors while they are busy allocating data multiple times to my account. TELKOM PLEASE KINDLY REFUND ME!!! I SHOULDN'T HAVE TO PAY FOR THE DATA THAT I BOUGHT UNINTENTIONALLY BECAUSE YOUR APP DOES NOT I REPEAT DOES NOT WORK PROPERLY. YOU NEED TO REVIEW YOUR DEVELOPMENT AND TESTING TEAM!!
