terrible being over charged and not receiving data that i purchased

<p>I am totally dissapointed with the service from MTN..i upgraded in Feb 2016- and since then have been getting bills of unexplained amounts - it hit me when for the past 2-3 months where i purchased data and added and did not receive it - i called the call centre and they advised the data disappeared - agent could not explain to me what my monthly subscription was or what was going on with my charges and referred me to a store.</p> <p>Initially i advised that a limit be put on the bill - so it does not increase</p> <p>i dont make any calls using airtime i only use the free minutes given.</p> <p> </p> <p>Now i heard that i was charged some packet switch and most of the amounts i dont understand</p> <p>i disputed it last month but to no avail was it corrected.</p> <p>i am disgusted and was billed R1598 that needs to be paid.</p> <p>i need a solution please assist.</p> <p>the 4 gigs that i purchsed in the past 2 months have disappeared - the agent have logged this query but im im not sure i will recieve the service i require REQ ********** </p>
