Very bad Service

I am an MTN client for more than 15 years and I did an application online for an additional contract on the 9th and immediately received a email saying application complete and sent for approval. TO this day I have no heard anything, I have sent emails, I have called and I get promised someone from sales will call but not one calls. Such poor service for a loyal client and I am rather disappointed. This is why people end up going to the opposition, which I think I am going to do.
