Bad & Poor Customer Service

I received a call from Telkom Sales( ********** ) on the 15th February 2019 about a mobile wireless router with 30G that is of Data for R199.00 per month. I was impressed because I thought it was a good deal. I received the router on the 22 February 2019. The router was not what I expected as it was a plug and play router. I called on Monday the 25th February 2019 to cancel the deal. I struggled to get through for more than an hour. When I suddenly spoke to a consultant and explained the reason of my call, she told me that I will receive a call from the sales people who will arrange for collection. She gave me the Ref No 367988 27. My Waybill No is THD ********** . I have been waiting ever since with no call coming from Telkom. I am afraid that Telkom might start deducting money from my account for the router I am no using. I called to cancel the deal within the 7 days of the cooling of period. I have been holding for more than an hour after calling their 10213 number as I am typing this on Hellopeter. I need them to collect their router. Their customer service is very bad and poor, imagine if I have to deal with them for the next 24 months.
