Pathetic Service

I went into the store at Hemmingsway East London on 25 May 2019 to buy a Apple iwatch got written confirmation of a price of R 6954 inclusive of VAT went back 3 times to even pay as I explained to the sales Lady Siya that was very cheap she confirmed that was the all inclusive price. The manager revues to take my call to resolve the issue at the watch arrived and they now want R1000 more than quoted and agreed on. I lodged a complaint with reference no. S4-33K21-IE7Q7 and also just ignore a sms to tell me its been transferred to someelse is all I receive. The consumber protection act should cover me on this but VODACOM service stincks I spend R6000. 00 a month with them but as my contract come to a end Ill move networks as this is pathetic service.
