bad service!!!!

<p><span style="color: #555555; background-color: #ffffff;">So i sent a cancellation form on the 26 January 2016 for my husbands samsung s4 to be cancelled as i will not be upgrading....received an email 3 February 2016 'sincere apologies on any inconvenience caused...we acknowledge your request and contract successfully cancelled. I was billed R99 in Feb. In March i got a statement and was billed again i do not have the statement with me for the exact amount but i can tell you it was more than the contract agreement amount!!!! I called the call centre and the person i spoke to should be thankful that i can't remember their name, assured me I will not be making another payment on samsung S4! To my suprise April month came and i was billed once again for the samsung s4. how ridiculous and what a *******! My Iphone4s was due for an upgrade 6April2016 i chose not to upgrade due to pathetic service. I sent cancellation form on 8 April 2016 and still got no email response back from ***. I was billed R99 for the iphone 4s so now whats next? im going to billed more than the contract agreement come end May! i will take this further if i do not get any assistance i have all my statements as well as emails that i have forwarded to a pathetic company. </span></p>
