Contract

I took a contract with u guys in December via homemark an agent by the name of Herold told me I have qualified for a Huawei y5 2018 which I will be be paying R149 every month and will be receiving 175 airtime for 24 months and he also told me I will be billed for 149in December to my surprise I was billed 175 I called Vodacom customer care and they told me I should take that up with homemark and at that time they were closed and opening up on the 6 January I became patient and thought my query will be solved to my surprise end Jan my bill went up now it was 179 I called again and was given a reference number *** and was told I will be contacted within 48 hours the next day I received an SMS saying I will be contacted by someone by the surname of Naidoo at 11oclock which she didn't later that day I received another SMS saying my query has been closed I again called Vodacom customer care and was given another reference *** which the same thing happened I received an SMS saying Someone by the surname of Naidoo is going to contact me which didn't happen again and received an SMS saying my query is closed . I kept on calling Vodacom customer care but still no luck and now I have just received my February statement and it says I have to pay 220 this is a ******* I don't wanna lie honestly I am not happy and all the customer service agents tell me is that it's impossible that I can pay 149 and receive a R175 airtime
