Horrible service with MTN Mondo

On the 04/06 after numerous attempts to return my router to MtN stores, i finally logged a collection with them. I was told “we have communicated with finance” no debit order will go off next month. The router was collected on the 14th of June, i am still told 21 days, i get that but can you tell me how many days to the cancellation, yoooooo outsourcing companies are the ****n pits
