Difficulty cancelling data contract

<p>My Smartdata 2.5Gb contract is coming to an end on the 27th of March 2017</p> <p> </p> <p>I have send the necessary cancellation documents via email to ********** on the 21st of February 2017 giving you guys ample time to proceed to cancel the contract. I am aware of an apparant 21 days for the cancellation to be processed.</p> <p> </p> <p>I did not get any response to my request. Not even a acknowledgement of receipt or anything. I phoned on the 24th of February 2017 to find out whether the forms was received or if a case has been opened. The lady on the phone could not tell me and she also could not put me through to anyone at the retention department. She advised me to email them again to ask whether they have received the necessary docs. Only 5 days later on the 1st of March I got an email telling met that they have not received the form and that I must resend it again. I did again on the 2nd of March 2017. Again NO RESPONSE.</p> <p> </p> <p>I phoned again on the 7th of March to hear whether the cancellation is being processed. The lady on the phone could still not tell me and told me to email them AGAIN.</p> <p> </p> <p>I don't know what to do. Can you please just tell me whether you are cancelling the contract. I WILL NOT be held financially reponsible if the contract is not cancelled before 27th of March when the contract rolls over to the next month on a month to month basis.</p> <p> </p> <p>PLEASE RESPOND URGENTLY! Because no in the call centres are capable of assiting me!!!!!!!!!!!</p>
