Six months left before I finish the contract

The joy since I am only left with 6 months to finish the contract. It’s been 1year 6 months of torture with the 081 number. The daytime data of 5 or 2 gig that disappears. The night data I am happy with but I am not renewing anything. I complained about the consultant that was rude and accused me of swearing at him when I said it’s nonsense that I use 1 gig of data on phone for a week or more depending on the usuage and finish 5 or 2 gig of day within 3 hours. I never got any response and the matter was never resolved as to why my day data are vanishing but it’s ok I am left with 6 months ??????
