Data package *******

Beware of the Deals you take with MTN, after taking a data package with them for 8G a month i receive 4G a month and still charged the package rate that i took out. Logged 5 calls and complaints got the reference numbers, spoke to the call centre and store managers nothing gets resolved but queries gets closed with resolved status.... Its now been 8 months.... From the intial fee of R89 it has increased to R95 also...
