Apalling service

I have a Telkom Mobile Business modem ****le to connect to the internet. It stopped working several months ago and I have been trying since then to get it repaired / replaced (I was only informed after about 2 months of phone calls to Telkom that there was no record of my complaint). In an effort to achieve this elusive goal, I have spent hours on the phone with Telkom dealing with countless call centre staff, had promises made to me of technicians coming out to assess, been into the store and waited while a technician fiddled around for about 1 hour with the modem, spoken to and left messages for call centre team leaders to call me back and I still have non-functioning modem. (None of the promises were ever fulfilled). Of course my debit order for the modem goes off like clockwork every month for something I cannot use.<br> <br> I am seriously unhappy with Telkom and quite frankly have no idea what to do anymore to get this resolved. <br> <br> Case reference number for any Telkom employees who might possibly take an interest in this is: ***3. Scary - I have quoted that number so many times to Telkom that I remembered it without having to refer to any document!
