Unprofessional consultants

I initially app**** for a contract with Telkom on the 31st of July 2017 and was told my credit check would be finalised within 48hours. 48 hours later still no phone call from the lady who was assisting me, I tried to follow up with no success but eventually established that my application was approved 3days after my application. On the 10th of August is only when I got a response that my application was approved however I was away but got back on the 15th of August and was at the store in Woodlands on the 16th. When I got there I found that they were offline they did however hand the products to me and said they would call as soon as they are back online to activate my WIFI 3 days later and I still haven't received a phone call, their phone keeps ringing non stop and at the end of the month I will be expected to pay for services which I still haven't used!
