Overcharged and Ignored!!

<p>My cellphone contract has been the same number and same Provider (Autopage) since inception in SA. Billing has been fine but the Internet Connectivity and Service (Call dropping etc) has been terrible and unresolved by MTN and Autopage for the last 3 years. In March MTN took over all Autopage contracts, and 1 month after this my 24 month contract with Autopage was up so I did a Number transfer and Upgrade with Vodacom.</p> <p>The single month my account was held with MTN I received a Data Switch extra charge on my Billing in excess of R1500 over and above my regular usage. In trying to resolve this issue: I need to call 808 from an MTN n umber so I borrowed a friends cell (Mtn account) and when prompted to enter the number associated with my query it responds that I have entered a wrong number...of course it does not recognize my number as I am now with Vodacom!! Also tried the same procedure from landline to ********** with exact same result, my number is not recognized. I have sent at least 15 emails to every MTN email address I can find requesting Itemised Billing/Assistance/ Credit/ all with same result. I receive an auto response with a reference number and promises that I will be called within 3wd... which NEVER happens! Been going on for months with no assistance or resolution.</p>
