disgusting service

I was an MTN client for almost 8 years and had switched over to other networks like cell C & Telkom. My contract is coming up for renewal but decided to switch back to MTN. I requested for a contract on the website on Monday. I was contacted approved and very well assisted by the lady. I had submitted all my documents on Monday as well. Since then I have tried contacting MTN telephonically with absolutely no success and also e-mailed continuously just getting return messages promising a call back. I have also sent my contact details on the website. Today is Thursday all I wanted was information for porting my no now or in 3 months. Little guidance required to say the least has now costed me money and a contract at my existing provider. Cell C provided me with the information but MTN 4 days later have not assisted me. I finally got a call today and to share my frustrations I said cancel my application and the response was “ I would send a request”. Absolutely nothing to identify why , why , why. Don’t you guys treasure clients and new business. Is there no concern as to why a client is angry??? If I am not contacted by a supervisor / senior manager I will take this matter to the social platform. This last sentence was posted 2 days ago with 3 new mails to customer care
