Disappointment in service NOT PROVIDED

Im extremely disappointed with the service I received or lack thereof at MTN Waterfall Mall Rustenburg... I got a router on 10/05/2018 & the package was a 10gig day data & 10gig night data package. My invoicing date is the 14th of every month as per my existing contract, however on the 14th of May I only received 5gig day data and 10gig night data. I went back to store a query was logged ref no. 1- ********** 7466 with turnaround time of 48hrs, on the 18th May I went back to store for feedback and I was told systems are offline so I called call centre and was told query has been escalated and I was given another ref. ********** 77 with turn around time of 24hrs, on 23rd May went back to store and was told query is still not solved and another one was logged with ref. 1- ********** 4916 with another turn around time of 48hrs... on the 30th I paid the FULL amount for the contract although I didnt receive the services I paid for, I called the call centre again for feedback on 30th May and was told the lady who captured application (Thato Mogomotsi) did so incorrectly and I need to have this rectified and i was given ref. 1- ********** 9496. Today is my second billing date since ive taken this contract and STILL I only received 5gig day data. When I went to the store I asked to see Thato Mogomotsi, when I explained my issue, she rudely told me there was nothing she could do and was arguing with me when I tried to explain to her that Ive been trying to sort this out for a FULL Month and she made an error. Instead of acknowledging the mistake she made, which was confirmed on two occassions with 2 different call centre agents. I even called the call centre as I was sitting in the store and she still didnt acknowledge her mistake after Minenhle from the call centre also confirmed there was an error in capturing. Today i was given another 2 references, one from call centre ********** 97 and another from Thato Mogomotsi the disrespectul, rude consultant that put me in this situation to begin with 1- ********** 1371. So this month again must I pay for services not received? And when MTN finally resolves thid issue will i get the 10gigs they now owe me for last month and this month? This is disgusting service really and Im extremely disappointed... your BOZZA NETWORK, is not bozza AT ALL!!!
