Misleading information!!!!!

Worst customer service experience!! I have been waiting for my issue to be resolved. My data sim contract expired in Feb and I called in to cancel it off . I spoke to a lady and she told me it’s done and that I will receive an email but nothing!!! I than called again after a work to follow up cause we humans and we have lives after all! And the person I spoke to said it wasn’t done so they had to cancel the contact . Why wasn’t it done in the beginning??? The only thing the First Lady knew best was to tell me to rate the level of service!!!!! And now I got a notification that cell c debited me and they did so thrice the money I was paying! The lady that actually resolved my cancellation told me everything will be done on the 03 April and when I called again today to find out why they deducting so much money she explained the situation and told me that I will be charged again month end of April the value of R600!!! I will not pay that money the lady who cancelled it told me the last pay day was the 03 of April !!! She must pay the 600 month end on my behalf . I have been a loyal customer with cell c for more than 5 years and this is the thanks I get! I would like this matter resolved and someone to get back to me ASAP! It’s appalling we still have people that treat customers like this
