MTN *****ing My Data/No Response to Queries

My MTN bundle (5gigs) loads on the 6th of every month. Every month my bundle is depleted within 2 days. When I check on the MTN app it shows that I used about 50mb of data in those two days but my whole bundle is gone. I have sent numerous emails to MTN customer care, they came back and told me my account is an SME account and I must forward my query to *** which I did but I have never received any response from this email. On 14 January I bought a gig of data as I am working from home, On the 15th January that gig was gone but I only used 47mb of it. MTN is *****ing from its customer's and then ignores our queries when we send them. I am so glad my contract is coming to an end next month, good riddance.
