Loaded DATA 5 times still not received but billed for it!

On the 07/02 I added a 3gb bundle via MTN Active (purchasing data this way is something I do weekly), after not receiving the data I called 808 who said to wait a bit longer. Added another 300mb bundle, nothing received. On the 08/02 I called 808 again who advised that there is a problem when loading Value Added Services for Data and Minutes and that it will be resolved. Friday 09/02 I called again, this time my query was escalated because according to the call centre agent it was impossible for data to take so long to come through, I agree. I was advised someone would contact me for the latest by Monday, 12/02. Still nothing, I called again twice yesterday and after being told the data loads were in a network fail status and I would have to pay the bill before I can query the data charges. Then I was told my query has been escalated again. Added yet another 2gb bundle but still NOTHING!. MTN I have had it waiting for this data, these charges have been billed to me and I have received nothing!!!!!! I have had to spend endless about of money purchasing smaller bundles cash in the hopes that I would receive my other bundles. I WANT ALL THESE DATA CHARGES REVERSED ASAP. I AM NOW SITTING WITHOUT ANY DATA
