CELL IS THE WORST SERVICE PROVIDER EVER

I have been trying to get my data contract cancelled for the past 2 months but with no luck. Because i relocated and iam not able to visit the branch anymore i send them an email beginning of Sept asking them to cancel my contract and nobody responds back to me but what they could do is to go and start debiting me double the amount that they should debit. How ridiculous is this, they are good at taking people's money but when it comes to customer service they suck the most. This is ********* business practise and ***** to customers. Back in September someone responded to my email requested some documentation inorder to cancel my contract which i sent to them but no one bothered to do anything with it and now today someone came back to me again requesting for the same documents. Do they realise that some of their clients are really busy and do not have time to duplicate work. My entire life i have never received such bad customer service especially for something that is so simple as cancelling a contract. i would never recommend cell c to anyone, my entire family uses cell c but now i have to switch them to another service provider asap.
