MTN why couldn't you help me!!!

Very unhappy with MTN to activate my roaming service Needed to contact them 4 times Every call takes excess of 15 min just to drop the call in my ear On the last call with Mandie I asked to speak to supervisor and I was told he is not available My request was to activate roaming told me the request loaded by Zandele and others was for a upgrade This was not the service I expected, as a customer for many years with 3 contracts. Now I am forced to leave SA on my business trip without roaming My wife's Cell roaming was activated within 5 min with no issues!!! Regards Andrew Ref nr from MTN: ********** 33
