No call or double data

I purchased a 250mb data package on the vodacom app and as per app it should be x2. Didnt receive the extra 250mb but purchased annother 100mb and got it x2. Phoned 111 and the first guy told me double your data does not exist anymore. Then spoke to someone else and they couldnt veryfi my account. Then requested to speak to a team leader who assisted but promised to phone me today but no call. Any data I use out of bundle will be for Vodacoms account as I PURCHASED my data bundle if Vodacom is too useless to allocate it it should not be the customers problem. And just annother thing.. stop lying to your customer and waisting their time to hold for afrikaans speaking consultants as you no longer have afrikaans speaking consultants as you can never get them on the line
