unwanted upgrades

<p>telkom sent out an sms to their clients in the Glen Marais area 4 weeks ago advising that they are doing upgrade infrastructe and that our services will be interrupted for a day or two, but its been four ways now and we have called them everyday and advise them that the line is still not working as it should, we work from home and this has set our business back allot. Telkom upgraded our line to a 10meg line and according to the technician we can't be on a line that high because of the distance from exchange to our house, our line was always on a 4meg and when we asked them to change it back, they say they cant change the line back. they are sending us from pilar to post just to get our line working. Telkom call centres are hopeless and they offer no help at all. on top of all this they send me an invoice for a month i did not use.</p>
