Pathetic Service from the store manager at Cell C BENONI LAKESIDE

What a bad service i received a cell c lakeside mall outlet, took my phone(Nokia 6) for repairs on Monday the 08.10.2018 and on Friday the 12.08.18 I got an sms that i need to go to to the store for a replacement. I went to the store and got assisted by Thabo apparently hes the manager there,he took the repairs papers and went away with them and came back to tell me that I have been credited with R3600 which I can use to buy another phone and I can add money if the phone I want is higher than R3600. I agreed to the offer and chose a phone to the value of R4600 and was going to pay R1000 extra. He then assigned someone to help me and the guy who was now helping me told me that my credit was R3200,i told him i was told of R3600 and not R3200 which by then i asked to talk to the manager who never even bothered to come and talk to me instead just hid in the office and got told hes busy. funny enough the so called manager never even bothered to explain to me that i can actually get the same phone without having to pay any extra money which goes a long way to show how hes used to ripping people off their hard earned money just to push his turnover,got told by the guy who was helping me who also promised to try and get the phone for me on Saturday but am still waiting even today. Called the customer complaints on Friday,got told i will get feedback on Monday which never happened instead i had to call to find out whats happening and there is no response as yet...As i type this im still without a phone because of the pathetic service from cell c lakeside mall benoni
