Harrased by Netstar

My name is Pulane Moyana. I used to have a contract with Netstar which i canceled due to very poor service and moved to cartrack where I am currently happy. However despite telephonically cancelling the contract, Netstar has tried on numerous times to debit my account and has now resorted to harrasing me with emails telling me that they have now handed my account to collections. I Pulane Moyana with does not have an account with Netstar. The fact that they still believe I have an account with them is owing to their poor administration which is consistent with the poor service I got when I used to have an account with them, before my husband advised me to move to cartrack.

Netstar kindly cancel my account with you from the date of the last debit order. I do not want to have an account with Netstar and I don't appreciate being forced into keeping the account with Netstar running when I canceled it long ago.
