Appalled with Telkoms customer service

I took out a cell phone contract on the 12th Feb of which i only received the phone on the 23rd (needless to say i got no feedback on delivery and constantly had to follow up ) However i then went to port the number at Telkom Kyalami on Friday the 23rd and since then i have had an inactive sim card with no service , of which i am currently being billed for , To date no one is able to resolve my problem , i have to constantly go to the store to get feedback , this is not customer service in my opinion , i am appalled , this is the worst service from any service provider i have eve received . i have no option now but to ask that you collect your phone and refund my money and i go to a service provider who can offer me a service . the manager at Kyalami is trying to assist but still no joy . i run a business and this is costing me money , let alone the petrol and time to drive to telkom to constantly ask for feed back . i want someone in a very senior position to call me regarding this A very disgruntled and unhappy customer
