No response to email complaint

I had an ADSL line installed at my house in August 2014. Since I wasn't home at the time of installation, I didn't receive the ****le that is included in my package. I have been to the Telkom store in Cresta Centre 6 times already to get a ****le and have walked out every time without being served. I go during my lunch hour as this is the only time available for me to go. I stand in the queue for that whole hour and don't get anywhere. I eventually just end up leaving cause I run out of time. The service at the counters are extremely slow and they clearly don't have enough staff attending to customers. <br> I emailed the manager last week to raise my frustration and asked if there was any other way for me to get this ****le. This is after all included in my package and I am paying for it!! I have had no response at all.
