Useless and poor service NX

Very very poor experience, my contract ended on the 15th March.Firstly I called and was told I need to complete a cancellation form and send it to the cancellation's department. I did just that on the 2nd February fine, after a week of not getting any feedback I decided to pop into a telkom shop, queue was very long, after 20 minutes of standing in a queue, an agents tells me they cannot assist me, I have to call the cancellation department, I called and I was advised that I need to wait for 21 days before following up. On the 5 March which was 21 days and still have not received any feedback, I called waited for 30 minutes before an agents answered, than an agent told me that the is no cancellation request on my profile, she told me she would escalate this issue for me, she told me she would sms me her email address so that she can escalate, waited an hour for the sms and the was nothing, called again waited for more than 30 minutes, the second agent I spoke to told me she cannot help me I must resend the form to cancellation, I requested to speak to her manager, she went to call her, came back and advised that her team leader Nokuthula will get back to me as she was busy with an escalation, till the next day I never received any call, so I spoke to and agent online, from a telkom online chat because I did want to hold for long, the agent gave me 180 telkom email address for me to escalate, I did just that and still did not received any acknowledgment of my email or feedback, now every day when I am in the office only I dont have network, so last week I decided that I am tired of not having network so let me query, I did that with the chat because when I am in the office I cannot even call telkom call center, so he tried to assist but eventually told me that they cannot assist because it is the building infrastructure that is causing signal issues and because it is a business they cannot install a boost, so I thanked him for trying and told him I am going to port out because. I spend most of my time in the office, I cannot afford not to have signal all the time, so I asked him about my cancellation request. he confirmed that the cancellation request was done, I was happy to hear that, so today I had airtime I am calling at the end of my call I get the sms I get every month for airtime balance, I check and my number is still on contract why because I have request to be moved to prepaid since the 2nd February, im tired of telkom, call center they lie , they take long to answer, cancellation department is no where to be found, no feedback on emails send and now before writing to hello peter I tried to call and was on hold for more than an hour.CAN TELKOM PLEASE PLEASE LEAVE ME ALONE, I DONT WANT THEIR SERVICES ANYMORE, CAN THEY PLEASE TAKE THEIR AIRTIME ND DATA, I WANT TO PORT OUT AS IN YESTERDAY, I WONT PAY FOR THIS DATA THEY GAVE ME, I DONT WANT IT PLEASE TAKE IT BACK BECAUSE I HAVE CANCELLED THE CONTRACT ON THE 2nd FEBRUARY, IT IS NOW 1 APRIL , PLEASE TAKE YOUR AIRTIME AND DATA AND LEAVE ME THE HELL ALONE, MY CONTRACT ENDED WHY DO I STILL HAVE TO DEAL WITH THIS USELESS SERVICE , TAKE YOUR AIRTIME I AM NOT GOING TO PAY, YOU ARE NOW INVADING MY PHONE, I WANT TO USE IT AS I WANT, SOMEONE HAD BETTER DEAL WITH THIS MATTER AS IN TODAY, I DONT WANT TELKOM ANY MORE, USELESS SERVICE.
