Service provided was poor consultant was rude

I called MTN customer service on the 19 March 2015 enquiring about the data bundles that I had on my account. On the 14th March I was credited with 100Mb , 100Mb night express, R100 and on top of that I had close to 22Mb on my account but on the 19th I notice that I had exhausted all the data and airtime and found it strange and called in and spoke to Monde Nzama who was just cluess and rude and could not even explain how my data bundles were consumed instead he kept on confusing me with all the information that he was giving me and requested to speak to the team leader and that time I was told that h was busy with an escalation and he promised that his team leader Ndumiso Tshabalala was going to call me on the same night or Friday as his system was not giving him detailed balance of my query. I have been waiting since from Thursday till now for the feedback with my query. I'm very disappointed as I feel that MTN does not care about their clients and we not being taken seriously.
