No device, payment deducted monthly

I had taken out two Huwai Tablet contracts from Telkom in October 2015. The day I purchased my item, the store had just opened and firstly had an issue with issuing me with an invoice for the product purchased.<br> <br> About a week later, I had an issue with one of the devices, so I went to the N1 City branch. I wanted the device to be exchanged as it was within the seven day time period. The guy, named Theo was extremely disrespectful and inconsiderate. I explained to them that I was unable to make it to the tygervalley branch as the seven day exchange policy took effect that same day. I had called the Tygervalley branch manager who arranged that I could leave the item. Theo refused to provide me with a invoice indicating that I have left the item with them. He locked me in the store and told me that he will be going home and dont care about me. I tried calling the store manager Nasief on a few occasions but never could get hold of him.<br> <br> Ever since then, I have been to the tygervalley branch many times, called them, emailed them, left voice messages but never received feedback.<br> <br> I am disappointed in the services offered, I am paying for an item that I do not have in my possession.<br>
