Incorrect non-free Customer support number given,

I'm experiencing dropped calls and slow download speeds. I called 173 from my cell number. The recording said I must call 1808. I called 1808 and after an unsuccessful mess to report my problem, I did an balance check and my balance dropped from R 63.50 to 56.64 I called 1555 ad reported the problem and received this reference number: 1- ********** 0674 I explained that I got the number from calling 173 and the lady said the free number is 808, not 1808 from a cellphone number. Worst is, I received an sms saying the problem was resolved but I still didn't get the credit. MTN,why do you give numbers on your recordings that costs us money, reporting problems on your network? I lost 18 minutes on this contract a couple of months back that disappeared and reported it to Alice van der Merwe, but she just didn't reply to my emails. Really unacceptable.
