Poor Service from Telkom Once Again

Telkom does not respond to their clients or get back to them,it is virtually impossible to get in contact with you guys! I have even tries submitting a call back request from the store with no feedback,I have had internet with you guys for 5 years! My contract is over and I finally decided to cancel due to the poor network,I have had this logged instore earlier this month and hope that this has been processed accordingly,I had also paid a R700 deposit at the start of my internet which is to be returned on termination of contract,I was advised the billing issue can only be processed once the cancellation has been processed however it is almost impossible to get through to you guys to deal with this,can you guys please contact me Nathan on *** to have my cancellation and refund processed,this is extremely urgent as I am starting a new job in February and need this sorted out before then.
