Croocks day light ******ies

Good day, please note that I have cancelled this contract long time I still get calls that I owe them. They owe me and have been deducting more from account and took it up with they accounts and they advised that they can see my account is not normal and not sure why they have been deducting more from my account and told me that I should be refunded till today I have not received any refund only sms from some debt collecting company and I have explained it to them and also said that there is something not right that Mr Price mobile should refund me am so fed up with this people really. They have said to me as well when I make payments on my clothing account I should give my cell number I will get discounts none happened cause the clothing store they have never heard of anything like that.
