Vodacom Pathetic Service

In November 2018 I received a call from a Vodacom agent offering me a Router with 5g data as well as a Huawei Y3 phone. I confirmed with the agent that I do not want to go over what I am currently paying for both my contracts, she confirmed within 5 minutes that it would be less, and that I can either keep or sell the phone as it would be free. End Dec 2018 my payment went off, R400 more than she confirmed, I phoned Vodacom on 1 January, by 7/8 January I got calls from Rewards telling me that the handset and router would be collected withing 7-10 working days and that my account would be credited with the R400 at end January. I had to phone Vodacom to arrange collection. End Jan 2019 my payment went off, this time with just over R300, so in total there is over R700 that needs to be refunded. I have been in contact with 2 Vodacom employees on the 082135 number, as well as employees from Rewards (Durban number). I was told that I will be refunded latest 8 February 2019. Today is the 11th February 2019, no refund, and I cannot get hold of the 2 employees on the 082135 number. I have phoned on 8 February 2019 to follow up, and was told I can expect a call on 9 February, on 9 February I called again and was once again told I can expect a call if not in the next 20 minutes differently by the end of that day. No Phone call and No Refund. I am currently paying for a router that an *********** agent sold me, that I do not have anymore. On Saturday I was told that Vodacom is still waiting for the OK to do the refund, but there are 4 credit notes. I do not want my account to be credited as CREDIT DOES NOT PUT FOOD ON THE TABLE!!! I have NEVER experienced such sad service from such a massive Service Provider.
