Greatly Dissappointed Tax Payer

I recently took a contract of R379 for 2 sim cards,one for 2Gig data the other for 60 minutes,60 SMS's 60 megabites. the package was supposed to be delivered to me before the 6th ,but MTN managed to deliver the package very late on the 11th ,and my benefits were loaded on the 12th then comes the 31st R379 is deducted from my account and from there nothing was loaded on my account till today .When I call customer help line I was told that it will be loaded on the 12th because it was delivered on the 12th and money is not deducted on the 12th but on the 1st instead, and they say there is nothing they can do as customer care consultants ,and it will go on like this for the next 22 months . What angers me the most is that used to buy 2Gig of data of telkom for R139 for my handset a since I have 20 Gig telkom wi-fi at home.The painful thing is that i can no longer buy data for my handset on the beginning of each month cause is money they deducting without proper service, so that forces me to run my transactions at home only ,once I exit my yard I wont connect to internet therefore my transactions freezes and life stops until the 12th. people must be on the lookout not to fall into a trap similar to mine because every one who calls you, or you call them are like con artist pursuing you to fall into their trap ,that's how they make business
