Bad service and not responding to my request

For many years the monthly invoices for my Cellphone contract, 3G contract as well as call line identity statement was e-mailed to me. Three months ago MTN stopped doing this for reasons unknown to me. I have to call the call centre every month and request that the invoices for the month are e-mailed to me. Every time I have called I requested that MTN must e-mail my invoices to me every month (like in the past) Promises are made that it will be done outomatically but nothing has come of it. I am inconvenienced it is time wasting to have to call MTN every month. My employer reimburses me for my Cellphone and 3 G cost but will only do so if I can submit the invoices and call line identity on a montly basis.<br> <br> As a long standing MTN customer this service is totally unacceptable for something that should be a simple straight forward procedure, without me having to call them every month.
